I am using Facebook's OAuth dialog to log in people in two of my websites.
Yesterday morning I discovered that the oauth dialog is failing for one of those two website, only when I try to connect with a mobile device (iphone and android).
The way I call the oauth dialog is identical in both websites, except from the App ID of course and the redirect url. Basically I redirect the user to:
https://www.facebook.com/dialog/oauth?client_id=xxxxxxxxxx&redirect_uri=http%3A%2F%2Fwww.xxxxx.xxx%2Ffbresult&response_type=code&scope=email
Normally the user is prompted for logging in with facebook and give permission to the app, and the be redirected back to my website.
This works perfectly fine on both sites if I use it from the Desktop.
When I call this url from my touch devices (iphone or android, they both fail) I am forcely redirected to the mobile version of the dialog (https://m.facebook.com/dialog/oauth?etc,etc).
However this dialog from m.facebook.com dies with 500 internal server error for one of the website. (so: one works perfectly with mobile oauth dialog, the other does not).
I tried to open the m.facebook.com/etc/etc from my desktop pc and I could indeed see the 500 internal server error response.
Should I try to login from the desktop (which does not redirect to mobile version) then the authentication procedure works perfectly.
At first I thought this might be a facebook bug and that it would have been fixed within few hours at most, but it's been now for at least 2 days and still does not work.
I think I could really appreciate some advice at this point. Thank you all in advance.

Excuse me for the confusing title. We have programmed App which runs with in the Facebook. It can be accessed over the desktop/notebook browsers. However it is not accessible/available if I login to the Facebook app on my iPhone and go to the APP list. Following scenarios does not work.
1) If somebody sends me the invitation to use the APP using Facebook message. If I now login to the Facebook-app on my iPhone and go to the messages and click on the invitation, I see the error. "Page not found". This works perfectly if I login to Facebook using browser (on laptop or iPhone)
2) On my iPhone, in the Facebook APP, if go to list of my APPs then our APP is not available in that list. (Other apps like candy crush and so on can be found)
Are we missing some configuration?
Thanks in advance.
Best Regards
You are talking about a canvas app?
Those are not available on mobile, and never have been. But you can specify a Mobile Site URL in your canvas settings – users on mobile devices, that follow a link to your canvas app somewhere will then automatically be redirected to that external address.
Little cave-at: This has been disabled on a larger scale by Facebook recently, because some people where using it to redirect users to malware sites. Therefor now you have to get your app “white-listed” before this will work. Check this bug report, the FB engineer mentions are form where you can request this: https://developers.facebook.com/bugs/1051463851558493/
I must use facebook integration within desktop app on OSX. I've used part of facebook sdk for ios and modified all ui elements to properly work on desktop.
I'm presenting facebook dialogs within webView, display is set to popup, and redirect url is https://www.facebook.com/connect/login_success.html.
Everything seems to work fine (all the dialogs are working after login, token and expiration date seems to be ok and are stored between web sessions) except for the facebook cookies which are always set to be session only (even with the keep me logged in option turned on). This means user has to log in to facebook everytime app is opened which is really frustrating.
I've already tried setting display to other values (touch, page) with no success. Probably all relevant settings in facebook app are checked (Native or desktop app?, Embedded Browser OAuth Login, Client OAuth Login).
so the question is if anyone has encountered same problem or might know the solution to make keep me logged in option working properly?
We are using the method described in https://developers.facebook.com/docs/facebook-login/login-flow-for-web-no-jssdk/ to log users to our web site.
It was working fine since the last week. Now what happens is that
in mobile devices it does not automatically redirect to our site
after the user logs in.
Instead, the FB server returns a "500 Internal Server Error" error.
But this only happens with the mobile version of the login page
(option display=touch), with the desktop version the redirection
performs well.
This works:
https://www.facebook.com/dialog/oauth?client_id={myAppId}&redirect_uri={myurl}
This doesn't work:
https://www.facebook.com/dialog/oauth?client_id={myAppId}&redirect_uri={myurl}&display=touch
As we didn't know if the service was down for whatever reason
or there was a problem with our FB application,
we have created another FB application and we have set the web site
to a known url: www.google.com.
Then we have tested the url:
https://www.facebook.com/dialog/oauth?client_id={myOtherAppId}&redirect_uri=wwww.google.com&display=touch,
and to our surprise it worked, resulting in a redirection to the
google search site.
But if we set our web site in both the test FB application and the login url, it fails again with the same "500 Internal server error".
So we suspect that there is something wrong with FB and our domain.
Could FB be blocking my URL when trying to redirect through the mobile version of the login dialog?
We would like to contact the FB support team directly by email but we are unable to find a way to contact them.
Can anybody give us a clue on this?
Sometimes it's because your app is in Sandbox mode.
I am testing our web application on OPera Mobile. We have a signIn through facebook link. It takes me to the login page, but after I enter my ID and password nothing happens. If I click on the login button mutliple times, it gives me too many failed attempts error. But after this my facebook account seems to be logged in.
If I login to facebook and come back to our application and click on login, nothing happens, I see a blank page. After I did Javascript debug, I could see that the FB.login() callback is not running at all.
Can any of you tell me what could be the reason?
Thanks,

Facebook Connect contains some browser sniffing (or "pseudo-browser-sniffing", detecting some features and making assumptions about what browser is used and what other features are available). They have functionality that uses HTML5's window.postMessage() which ought to work just fine in latest Opera on both desktop and mobile, but due to the unfortunate sniffing approach they send Opera down another branch in their script. To be fair, this is for historical reasons, the postMessage() support was in flux for a while while HTML5 was shaping up and getting agreement on all details, so there are probably still some implementations (earlier Opera and IE versions?) that are still in use and would not work with Facebook Connect's JS.
Ideally, Facebook would fix this. I will follow up with Opera (to double-check that what I recommend Facebook should do will work on Opera Mobile) and Facebook (to try to get their browser detection adjusted).
I'm seeing a problem requesting permissions with Facebook connect on iPhones. Everything had been working fine and then it just started out of nowhere. I can't seem to sort it out, so I posted it here to see if anyone's experiencing the same issues? I'm trying to log users into a mobile website and here's what I'm seeing:
On Android, everything is A-OK, as are regular web browsers.
On the iPhone 3, users get the login page ok, but are not redirected to the request permissions page, just to mobile facebook. If they leave and come back and click on the login button again, they are taken to the request permissions page, and after they allow/don't allow, they are taken back to our site. This is also the same for iPad users
On the iPhone4, users get the login page ok, but are not redirected to the request permissions page, just to mobile facebook. If they leave and come back, they are taken to the mobile facebook site and never are prompted for their permissions.
Highlights:
Everything was fine 3 weeks ago
Everything is still fine on Android using the very same FBConnect url, but it blows on iOS
What happens on iPhone 3 is different that what happens on iPhone 4
I've tried doing this with 3 different urls, but StackOverflow will only let me put 2 in here because I'm a new user:
http://www.facebook.com/dialog/oauth?client_id=[OUR_CLIENT_ID]&redirect_uri=[OUR_URL]&display=wap&scope=email,user_location,read_friendlists,publish_stream,offline_access
http://m.facebook.com/dialog/oauth?client_id=[OUR_CLIENT_ID]&redirect_uri=[OUR_URL]&perms=email,user_location,read_friendlists,publish_stream,offline_access";
The other URL was similar to these, but used the graph API
Anyone have any ideas?
Thanks!
Facebook has since removed the WAP interface and replaced that with Javascript SDK interfaces for Android and iOS, and now normal wap enabled phones have been shut out.
