I have set up a google cloud sql server using the tutorial on youtube. However, Whenever I try to connect to it through the browser, the connect to it through the browser, the error i am getting is ERR_CONNECTION_REFUSED . The firewalls I have set up correlate to whats in the browser. I can also SSH into the VM. But the VM always rejects my connection. I have been trying for days.
Here are my VM Settings allowing http connections
Here is my VM External IP Address
Here is what the browser tells me when i attempt to connect.
Are you referring to this video https://www.youtube.com/watch?v=_kQXgjIfLgo?
In that video there are some steps missing such as install the web server (e.g. Apache) and PHP in the VM. After you install them, you can execute the following command in the VM:
php /var/www/index.php
If it works you can see the source code of the resulting page and if not you'll have an error to solve (maybe a package to install like php-mysql).
Once you can see the resulting page in the VM you can try to load the page through the browser of your machine. If it still doesn't work there is an Apache or network misconfiguration.

Unable to run the test for the webapps running in cloud ( application is accessible via browser only through VPN). Getting error.
You must first setup a tunnel from testRigor to your machine, then try accessing the page.
Read the tunnel documentation.
Set up a tunnel on your machine.
Request a port from testRigor support
Then run your test

i’ve created an instance that runs on a linux virtual matchine
i’ve also installed cockroachdb and nakama on that vm and started the node and nakama server there
i’m using oracle cloud infrastructure, i added security list to it to be able to access it through internet and now when try access it through the internet it shos me my server like this :
and now i dont know to to connect to this ???
i have the client in using and it doesn’t connect to it
and when i run it, it shows me this error
i also added the nakama port 7350, and the dashboard 7351 to the security list to have access to them through oci cloud and now the dashboard looks like this
where is the issue and how should i fix it ??
If you are using platform images, both Linux and Windows come with the OS firewall activated and allow very few services.
Open the ports on the OS firewall and try again.
I did a fresh installation of curity 7.1.0 on a Linux VM. it installed without any issue and started fine. However I am not able to connect it using admin console.
error:
Secure Connection Failed
An error occurred during a connection to xx.xx.xx.xx:6749. PR_CONNECT_RESET_ERROR
A RESET_ERROR often indicates a problem with the infrastructure in my experience.
You can try the following
Clear the cache of your browser
Test with a different browser
Check network settings, i.e. firewall, VPN, proxies, port openings...
I'm a new comer to using the overseas server. Recently I bought a vps from virmach in order to see foreign websites like google and wiki.
I've been trying for a long time configuring my shadowsocks on my server.
However, when I was using shadowsocks-qt5 to connect my server, it was timeout.
And of course I can't access google correctly.
What I want to ask is the reason why I failed.
Here are things that I do remember to do:
stop the firewall on both computers;
build the .json file which I referred to blogs in China.
Here are the outline of my shadowsocks.json on my server:
{
"server":"0.0.0.0",
"server_port":8388,
"local_address":"127.0.0.1",
"local_port":1080,
"password":"XXXX",
"timeout":600,
"method":"aes-256-cfb"
}
Other useful(maybe) information:
my client OS version: Ubuntu 18.04.3 LTS
my server OS version: Ubuntu 16.04.6 LTS
the client I choose is from: https://github.com/shadowsocks/shadowsocks-qt5
I could not help but wandered, are there any other possible reasons I've forgot? Can anyone inform me some helpful details to solve this puzzling problems? Thanks a lot!
I have not set up my own VPS but I have instead subscribed to the server provided by caonima.io, so I can't speak for any server related issues. Additionally, I have no affiliation with caonima.io. I did however successfully set up my client on Ubuntu 16.04 after having some issues connecting to GFW-blocked (China's Great FireWall) websites.
From what I understand from my solution, the client configuration is NOT the only step of setup. There are two layers of proxy access that need to be completed:
Client Configuration. Configure your client with the server and connection information. A successful connection looked like this for me with my command line interface
shadowsocks-libev command line client successful connection
System or Browser Proxy Configuration. You will need to configure either your browser or web access tool to use a proxy, or set system-wide proxy settings. To set system wide proxy settings, go to system settings > network > network proxy and enter the proxy information. Setting Socks host to localhost:1080 resulted in successful GFW-blocked website access (as shown below)!

I created a Google dataproc cluster. After logging into master node I started spark-shell then trying to access spark history page using
http://<external_ip_masternode>:4040
It get redirected to
http://<hostname_mastername>:8088/proxy/application_1487485713573_0002/
Browser is rejecting with error "DNS address could not be found." which is understandable.
Following are VM instance setting
Public IP type Ephermal
tcp:4040 opened in firewall
ip forwarding Off: Unable to edit this configuration
Following troubleshooting done but did not help

To view Hadoop web interfaces in Dataproc, it is recommended to follow the instructions for running an SSH-based SOCKS proxy: https://cloud.google.com/dataproc/docs/concepts/cluster-web-interfaces
If you follow the instructions there, it'll also have you run a separate browser session using your SSH tunnel, and sets hostname resolution to occur on the VM side of the tunnel. That way, all the links in the Hadoop pages will automatically work, since they all reference each other using internal hostnames, and intentionally avoid any dependency on "external IP addresses".
Using the SSH tunnel is also much more secure than opening up firewall rules to visit the unencrypted HTTP traffic directly coming from the Hadoop HTTP servers (if you accidentally open up your firewall rules too broadly, then other people on the internet will be able to access your external IP addresses, and even if you don't, attackers could see your unencrypted web traffic served up by the ApplicationMaster, HistoryServer, etc.).
