Just installed a SSL certificate and when I try to access to my fmbl app through https connection I can't see the application, the page is blank and I'm losing lots of users and the rate of my app is going to the deep down.
However, if I access to the app through http (non ssl) I can see without problems.
Thanks!
Have you solved?
'Cause i think the problem is arise by Chrome.
If your application has a self-signed SSL cert and you open it on chrome you'll receive a 501 error message. Chrome should show an alert message whit a 'continue' button to enter the app, but this doesn't happen when chrome call an https resource from an iframe.
Is it a self-signed certificate? For some reason, FB doesn't support those, and you'll need a certificate which is signed by a CA.

Since recently I can not test applications on localhost. There is no canvas url anymore to be set, only secure canvas url and it asks for https url. Even test apps do not have this option. So I have to buy another ssl and domain for testing pourposes only? If someone has the same problem or a solution please let me know. Cheers!
Just put in https://localhost and accept the unsafe message in the browser, you don´t need to buy a certificate.
You can also use a self-signed certificate, as explained in other threads:
create a trusted self-signed SSL cert for localhost (for use with Express/Node)
How do I allow HTTPS for Apache on localhost?
Thank you luschn for pointing that about self signed stuff out because just putting https://localhost will not work anymore.
It seems that facebook made some changes and that you can only test your apps on localhost if you create a self signed certificate with openssl tool. Then you can enter in secure canvas url something like https://localhost:3000/ and in app domains localhost and it seems to work. Other than creating selfsigned certificate I could not make it work on localhost.
I'm developing a Facebook canvas app. I don't have a SSL certificate so I've been using a plain http:// URL + sandbox mode for the creation and testing process.
Suddenly I realized my Facebook account turned to Secure Browsing mode and I'm unable to turn it off via Account Settings >> Security >> Secure Browsing. There is no "edit" button. None of my co-workers experienced the same problem. Their Secure Browsing option is off, editable and the app is visible. Anyone familiar with the same issue?
If you're testing your app you shouldn't really need to disable HTTPS, nor is that really a representative test if you're using HTTP but almost all your users will be using HTTPS (as is the case with Facebook)
It'd be better to get a free cert from startssl.com or similar free CAs, use OpenSSL to generate an in-house CA or self-signed certs, or accept the certificate warnings from the default cert that ships in your webserver, if any, than to disable the secure browsing option on your Facebook account for this purpose;
As for the option itself in the Facebook setting, that's somewhat off topic for here, and I'm unsure what the exact status is but I believe the option to browse Facebook insecurely is being phased out
Another option for testing is to run a test server with a separate proxy to your production environment (e.g nginx) for test purposes and log all the traffic to that server for debugging
Currently i am creating an sample facebook application. The problem is its asking for my application url in two types. Canvas url and Secure canvas url i had hosted my application on this link Fb app url but the hosting is not providing me ssl i.e. the link with https Because of this problem i am unable to include the Secure canvas url
How can i overcome this issue. How can i solve this. Is there any way to submit the facebook application without secure canvas url or is there any free webhosting site which also provides ssl (https). Please suggest me
try heroku . Facebook provides you that option while you are registering your app.
no you have to get the ssl certificate to secure url
check this What is SSL and what are Certificates? and Https connection without SSL certificate
this is Free SSL Certificate :by Comodo for 90 days but never tried by me
I am working on my first app for Facebook and facing (probably) with the SSL problem. If I am testing the app, so it's working well. But then I wanted to test the app by my friend - so I assigned him the role "Tester", he accepted it and I sent him the link to the app.
If he opened the app, he got the error The website is not available - Error 501 (net::ERR_INSECURE_RESPONSE): Unknown error
I started google it and it looks that the cause is the missing SSL certificate on my hosting, where the app is stored.
BUT - how is possible, that the app is working me well without the SSL and to my friend doesn't? If the SSL is required for Facebook apps, why I didn't get the same error?
(I set Secure Canvas URL: to https://example.com/fb-app-directory/, however I don't have at this domain and hosting any SSL certificate).
I never used before SSL. I bought the domain name on Namecheap and hosting on Hostgator. So now, I should buy a SSL certificate from the offer (http://www.namecheap.com/ssl-certificates.aspx) of Namecheap, right?
Would be suitable for the Facebook app the cheapest one?
Look, this SSL problem can only be solved by purchasing a valid SSL certificate or looking for a server which can host your app and is SSL certified such as:
phpfog.com - Provides you with some limited space and database service.
heroku.com - Does not provide any storage space for saving dynamically generated data. To have that service, you have to buy the Amazon buckets service which, again, is a costly affair.
If you don't want to invest any money, I would recommend that you go with phpfog - it is easy and its documentation is pretty good.
You should buy an SSL cert in order for everyone to be able to access your app. Your friend probably has his settings set so that he browses Facebook securely, in this case he is hitting https://example.com/fb-app-directory/, not your actual URL.
The cheapest one isn't the best one, but it should work as long as it's valid. I would suggest using Heroku though, as that way you get everything you need - for free :)
Use a proxy in heroku.com and bring your page in secure domain as https://yourapplication.herokuapp.com/
"Starting October 1, 2011 Facebook will require a valid SSL Certificate for all pages and applications hosted outside of Facebook."
http://www.wpcode.net/fb-ssl.html/
Maybe you are visiting your application with http://apps.facebook.com/... and your friend is visiting with https://apps.facebook.com/....
Another possibility is that your friend has checked "Browse Facebook on a secure connection (https) whenever possible" under "Account Security".
Try ngrok. It exposes a local web server with just one command:
ngrok 80
After this you can access your localhost like this: xxxxxxxx.ngrok.com
I configured my web server to use HTTPS instead of HTTP. I used openssl to generate an X509 certificate and private key. When I connect using FireFox it warns me of an "Untrusted Connection" and allows me to add an exception to continue. When I connect using my iPhone's Safari web browser it does the same thing. I hit accept to the security prompt and it works fine.
I add the web page to my home screen so that I can run it as a web-app. When I open the web-app I see the following prompt:
Cannot Open MyWebApp MyWebApp could not be opened. The error was: "The certificate for this server is invalid. You might be connecting to a server that is pretending to be mydomainnamehere.com" which could put your confidential information at risk.:". CLOSE or RETRY
If I hit close the web-app closes. If I hit retry I see the prompt again. There is no option to trust the site and continue. How can I get this to work? I'd like to use HTTPS to encrypt the sensitive data. It is a private site I use to access files remotely. It is not intended for public use.
There are two solution. 1) use a trusted certificate and 2) is to add the untrusted certificate to your iPad. This way your iPad will consider it as trusted.
Download the certificate (with Chrome for example), put the cert as an attachment on an email. Open this email on your iPad and click the attachment/cert and install it. Thats it!
