I have searched for this question, but none of the responses help me.
Following the tutorial, I have created a new bucket (www.stepwiserefinement.co.uk) and it contains a static site, including index.html and error.html.
I have used the Console to set these as defaults for the base url and unknown files.
When I access the http://www.stepwiserefinement.co.uk URL, I get an XML listing of the files; I should be seeing index.html.
gustily correctly reports
{"mainPageSuffix": "/index.html", "notFoundPage": "/error.html"}
but if I access the domain with no path, the response is
<Error>
<Code>AccessDenied</Code>
<Message>Access denied.</Message>
<Details>
Anonymous caller does not have storage.objects.list access to the Google Cloud Storage bucket.
</Details>
</Error>
No https, no load balancer needed.
Missing something.
Suggestions please.
There's multiple issues here.
Your site still loads in HTTPS when you put it in the browser. The connection is somehow upgrading you to SSL. And if you're in SSL, you need the load balancer. As opposed to these instructions without load balancer. Maybe you have SSL turned on with your registrar or somewhere else.
I only get 404 error. Not sure how you got "Access denied". But it could also be a secondary issue because when enabled properly, no access control is present. For example, it says here under step 3 "selected Uniform for Access Control". This removes access control.
Let us know if you followed the last article completely
Edit: Also, out of curiosity, try making the bucket public (without Uniform), if it doesn't work above.

I am trying the simplest example I can, pulled directly from their website. Here is my entire html file, with code taken exactly from https://peerjs.com/index.html:
<script src="https://unpkg.com/peerjs#1.3.1/dist/peerjs.min.js"></script>
<script>
var peer = new Peer();
var conn = peer.connect('another-peers-id');
// on open will be launch when you successfully connect to PeerServer
conn.on('open', function(){
// here you have conn.id
conn.send('hi!');
});
</script>
In Chrome and Edge I get this in the console:
peerjs.min.js:64 GET https://0.peerjs.com/peerjs/id?ts=15956160926060.016464029424720694 net::ERR_CONNECTION_REFUSED
In Firefox I get this:
Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://0.peerjs.com/peerjs/id?ts=15956162489620.8436734374800061. (Reason: CORS request did not succeed).
What am I doing wrong?
#reyad has requested "a full trace of requests and responses". Here's what I see in my network tab in Firefox:
And here's Chrome:
And a tiny bit more Chrome:
[Note: It would have been better if you could provide a full trace of requests and responses. This problem may occur for several reasons. I'll state two solutions. So, try those. If those doesn't work, provide full trace of requests and responses.]
1. First Solution:
Sometimes, this type of error occurs because of self-signed certificate. To solve this problem, open developer tools/options, then go to network tab. You'll see a list of requests. Select the request which was failed because of CORS(i.e. which gave you this Reason: CORS request did not succeed). Open it(i.e. click it). If your problem is related to cert you'll see the following error message:
AN ERROR OCCURED: SEC_ERROR_INADEQUATE_KEY_USAGE
To solve this problem, go to url that is the reason of this problem and accept the certificate manually.
2. Second solution:
Check the request(which is the reason of CORS) in the network tab of developers tools/options(same as described in 1. First Solution). You'll find a Transferred column. See, what's written in the Transferred column of the failed request. If it is written Blocked By Some Ad-Blocker, then disable the Ad-Blocker. Your request will work fine.
[P.S.]: These solutions are proposed on assumptions. Hope these works. If these two do not work, then please provide more info about requests and responses. And also check this.
3. Third and final solution:
[Note: This solution may not solve your problem directly, but it'll give you alternative solution and also insight about what your problem is and how to work around it]
Before reading the solution below, read this to understand how Access-Control-Allow-Origin works(it is the reason for CORS error).
Let me first explain how peerjs works:
PEERJS works based on PEER ID. So, you've to get some PEER ID either from the PEERJS CLOUD SERVER or you've to provide yourself one in the PEER CONSTRUCTOR i.e. new Peer("some-peer-id"). Peer id has to be unique, cause its necessary to detect all the users uniquely. And, peerjs uses this PEER ID to send and receive data from user to user.
Now, you should know that, you're using PEERJS CLOUD SERVER to get/generate unique peer id which is the default server PEERJS uses unless you specified some other server to use.
Now let me explain why you're facing this problem:
As you already know how CORS works, you may have already guessed, that https://unpkg.com/peerjs#1.3.1/dist/peerjs.min.js(the downloaded js file) is calling https://0.peerjs.com to retrieve/generate new unique PEER ID. But, this request by https://your.website.com does not have Access-Control-Allow-Origin access for some reason, it may also be a middleware problem. So, its difficult to tell where the problem is actually occuring. But one thing for sure, it's not your fault of writing code :D.
I hope all the concepts is clear to you I've stated above.
Now, to solutions:
Alternative-appraoch-1 (Using PEERJS CLOUD SERVER AND Your own provided id):
In this approach you've to generate your own unique PEER ID. So, "https://your.website.com" does not have to call "https://0.peerjs.com" for unique peer id. [Note: make your peer id large enough so that its always unique, at least 64 chars long]
In this way, you can avoid the CORS problem.
Update:
I just saw an new issue in github, which says the public peerjs cloud server is now unstable or does not work properly. It just gives error like: Firefox cannot establish a connection with the server at the address wss://0.peerjs.com/peerjs?key=peerjs&id=123222589562487856955685485555&token=ocyxworx62i and in Chrome: Error in connection establishment: net::ERR_CONNECTION_REFUSED. For details check here. So, its better, you use your own server(see the next approach).
Alternative-appraoch-2 (Using your own peerjs server):
You can host your own peerjs server instead of PEERJS CLOUD SERVER. In this way, you can allow access to anyone/any website you want. If you want know how to host a peerjs server, you may visit here.
[P.S.]: I have studied pearjs issues in github. After reading all those issues, it seems, it is better to use your own server rather than using pearjs cloud. There are a lot of various problems with each new release of peerjs. And mostly related with connection with peerjs cloud and also peerjs cloud is not stable I guess. They were hosting it in 0.peerjs.com:9000 before(not secure). But now in 0.peerjs.com:443.
I haven't use peerjs before nor set up peerjs server. If you want to set up one, I hope the community would be able help you on how to do that properly.
What I understand from your question is that there is an issue of (CORS => Cross-origin resource sharing ), Maybe what I am suggesting is not very intuitive.
First : download the "https://unpkg.com/peerjs#1.3.1/dist/peerjs.min.js" in your local directory . and then incklude the local javascript code to the html.
like: <script src="./peerjs.min.js"></script>
Second :
you are using var peer = new Peer();
but please provide an extra unique id from your side. for example, I just created a random id and provided it.
StackOverflow link: https://stackoverflow.com/questions/21216758/peerjs-set-your-own-peerid#:~:text=1%20Answer&text=Provide%20a%20peer%20id%20when,to%20under%20Create%20a%20peer.
var a_random_id = Math.random().toString(36).replace(/[^a-z]+/g, '').substr(2, 10);
var peer = new Peer(a_random_id, {key: 'myapikey'});
Third : the best option is to run PeerServer: A server for PeerJS of your own.
If you don't want to develop anything, just enter a few commands below.
Install the package globally:
$ npm install peer -g
Run the server:
$ peerjs --port 9000 --key peerjs --path /myapp
Started PeerServer on ::, port: 9000, path: /myapp (v. 0.3.2)
Check it: http://127.0.0.1:9000/myapp It should return JSON with name, description, and website fields.

Try to troubleshooting QuickBook's Web Connector by following helping URL: Click Me. When I try to Add an application into Web connector getting following error: "QBWC1048: QuickBooks Web Connector could not verify the web application server certificate. QBWC1051: The new application was not added"
QuickBook throws the 1048 error because it is unable to complete a GET request at the AppURL that specified QBFS.qwc file. This is because test.developer.intuit.com restricts GET requests via the SOAP API.
To get around this, include a parameter in the .qwc file, and set it to the same value as your AppURL without the URL path.
For example, if your AppURL is https://mycompany.cs1.force.com/services/Soap/class/myApiClass, then set CertURL to https://mycompany.cs1.force.com.
This is the solution suggested by the QBWC log file, and it worked for me.
Reference URL
I found I had this problem because my software was trying to load the file
http://developer.intuit.com/uploadedFiles/Support/QBWebConnectorSvc.wsdl
which no longer exists. :(
So I got a WSDL from
https://test.developer.intuit.com/QBWC/TroubleshootWebServiceFS/Service.asmx?wsdl
and put it in my Site's root directory, then changed my code to point there, and it worked.
I want to prevent the user from accessing the Hidden Directories like Scripts, Contents, aspnet_client directly from the browser in a asp.net mvc 2 application. Currently whenever I try to access the above mentioned Hidden Directories it is returning the following error message:
403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.
I want to show "404 Not Found" error page whenever one tries to access the above mentioned hidden directories.
Can anyone help me with to resolve this issue?
When attacker try to access the file with some random name, if given file name not exists then it will give error like "404 File not exists". if file name exists but don't have access to file then it will return error like "403 Forbidden" error. so attacker get idea of the file and file directory.
So the application should be capable of handling this issue
Solution is to show the return response in different way, recommended to show as 404 error.
To do this in IIS we can add customerError configuration in the web.config file.
Please check the below article for the details of issue and solution.

I've followed the procedure documented at "Adding new ways to share content"
...but keep getting an error:
Failed to preload gadget http://....
Detailed error: 400 Gadget is not trusted to render in this container. cre.iruntime:cre.iwidget.event:cre.wire:cre.iwidget:cre.iwidget.itemset:cre….ibm.connections.ee:ibm.connections.ee:container.nongadget:open-views.js:4

This looks like some sort of trust problem with external servers, but my other gadgets (embedded experience & home page gadgets) on the same external host are all working fine.
What have I missed out in the configuration?
OK, shamefully, it looks like I missed out swapping the security attribute whitelistEnabled="true" to whitelistEnabled="false" in:
/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/connectionswwCell01/LotusConnections-config/opensocial-config.xml
Here:
<security whitelistEnabled="false" featureAdminEnabled="true">
More details in this slide: How to add your own OpenSocial Gadgets to IBM Connections.
Of course, in a production system, you'll have to checkout the opensocial config using wsadmin.sh, edit, checkin & restart.
I'm trying to generate a Perl library to connect to a WebService. This webservice is in an HTTPS server and my user has access to it.
I've executed wsdl2perl.pl several times, with different options, and it always fails with the message: Unauthorized at /usr/lib/perl5/site_perl/5.8.8/SOAP/WSDL/Expat/Base.pm line 73.
The thing is, when I don't give my user/pass as arguments, it doesn't even asks for them.
I've read [SOAP::WSDL::Manual::Cookbook] (http://search.cpan.org/~mkutter/SOAP-WSDL-2.00.10/lib/SOAP/WSDL/Manual/Cookbook.pod) and done what it says about HTTPS: Crypt::SSLeay is instaleld, and both SOAP::WSDL::Transport::HTTP and SOAP::Transport::HTTP are modified.
Can you give any hint about what may be going wrong?
Can you freely access the WSDL file from your web browser?
Can someone else in your network access it without any problems?
Maybe the web server hosting the WSDL file requires Basic or some other kind of Authentication...
If not necessary ,I don't recommend you to use perl as a web service client .As you know ,perl is a open-source language,although it do support soap protocol,but its support do not seem very standard.At first,its document is not very clear.And also ,its support sometimes is limited.At last,bug always exists here and there.
So ,if you have to use wsdl2perl,you can use komodo to step into the code to find out what happened.This is just what I used to do when using perl as a web service client.You know ,in the back of https is SSL,so ,if your SSL is based on certificate-authorized,you have to set up your cert path and the list of trusted server cert.You'd better use linux-based firefox to have a test.As I know ,you can set up firefox's cert path and firefox's trusted cert list.If firefox can communicated with your web service server succefully,then,it's time to debug your perl client.
To debug situations with Perl and SOAP, interpose a web proxy so you can see exactly what data is being passed and what response comes back from the server. You were getting a 401 Not authorized, I expect, but there may be more detail in the server response.
Both Fiddler http://docs.telerik.com/fiddler and Charles proxy https://www.charlesproxy.com/ can do this.
The error message you quote seems to be from this line :
die $response->message() if $response->code() ne '200';
and in HTTP world, Unauthorized is clearly error code 401, which means your website asks for a username and password (most probably, some website may "hijack" this error code to cater for other conditions like a filter on the source IP).
Do you have them?
If so, you can
after wdsl2perl has run, find in the created files where set_proxy() is called and change the URL in there to include the username and password like that : ...->set_proxy('http://USERNAME:PASSWORD#www.example.com/...')
or your in code, after instantiating the SOAP::WSDL object, call service(SERVICENAME) on it (for each service you have defined in your WSDL file), which gives you a new object, on which you call transport() to access the underlying transport object on which you can call proxy() with the URL as formatted above (yes it is proxy() here and set_proxy() above); or you call credentials() instead of proxy() and you pass 4 strings:
'HOSTNAME:PORT'
the realm, as given by the webserver but I think you can put anything
the username
the password
