We have a post on a FB wall. It points to http://tinyurl.com/{something}.
When the link is clicked in a non-mobile web browser, it works fine: TinyURL redirects the user to our web site using the appropriate URI including a special querystring.
When the link is clicked in a mobile web browser on my Android, it fails with the error in the title of this question.
When the link is clicked in the FB native app for iPad and in Safari on the iPad, it works fine.
I have tried adding our URL to the Mobile Web setting in the Basic Settings tab of the FB App configuration. That results in all links pointing directly to the root of our web site with a funky set of parameters in a querystring -- in other words, it doesn't follow the TinyURL in that particular case. The funky parameters include "refid", "ref", and "ft".
So primarily my question is: Why, when I specify the URL in the Mobile Web setting as described in the previous paragraph, does it redirect to our main URL instead of the TinyURL link originally called for?
I think this is something Facebook broke very recently (perhaps even today?). When a user clicks on any links to our app from inside the Facebook native iOS app, they get this error "Either this application has not configured its Mobile Web URL or the URL could not be verified as owned by the application. Unable to redirect." We had never set a Mobile Web URL previously, and everything had been fine since we launched the app over a year ago. We sent all mobile clicks to the same URL's as desktop browsers and handled the mobile rendering server-side. We have not changed our application domain inside the App Settings or anything like that.
In the App Settings, can set a Mobile Web URL to our homepage and the link works (and the error message goes away) but that's not the desired behavior at all - it would mean that all links end up at the same Mobile Web URL regardless of what the link was!
Was this change made on purpose by Facebook and if so why? There's been no mention of this whatsoever on the Developer Blog.
Update 3/21 8:10am PST:
I've since found this to be a widespread problem, not just for a few apps. Just by clicking around I've seen this error on posts to weather.com, youtube, msn.com and a dozen others. It happens on both clicks from the Timeline as well as the News Feed (although strangely sometimes the same post works on one, but not the other!), and from the m.facebook.com mobile web app as well as the native iOS app.
I commented on http://developers.facebook.com/bugs/302635863137683 but no word from Facebook yet. I can't believe more people aren't talking about this right now, this is a major bug.
In your app, go to Settings -> Add platform -> Website
Add both, Website URL and Moblie Website (Yes, you need these both), then your app will be able to be opened from facebook native app.
You will also need the FB Canvas.
Same here, I recently noted that all links of items shared with our Adroid or iPhone app are broken. This only happens with the mobile version of Facebook the Desktop web version is still working. What is actually wrong on the mobile version is that the original shared url is replaced with a m.facebook url that ends with "?ref=unknown&refid=0&ft=fbid.332036910178718%3Ainterface.m_touch%3Ac.m" When user click on it Facebook is redirecting the user to the App's "Mobile Web URL" + "?ref=unknown&refid=0&ft=fbid.332036910178718%3Ainterface.m_touch%3Ac.m" instead of the original shared url.
My opinion is that this is an issue of Facebook that is redirecting the url to the wrong location, "Mobile Web URL" instead of the original post url.
Ok not working. What is going on, 1st directed to something about itunes url. I am on an Android not an Iphone. Sad state when an disabled person is unable to gain access the same as others. This is bad for all users.

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 created a facebook and placed it on my facebook brand page, I also created a post on the wall of that page with the link to the app.
all works well until people started calling me saying that when accessing using FB iPhone app it will redirect to an error page "the page your requested was not found"
I tried adding a link (same page) to the "Mobile Web" link of my app in the FB Developer App.
it still doesn't work..
I need people accessing the app page to get some content.. I know it is possible but cant find how..
thanks for your help
Tabs aren't supported via the app or mobile site. Best you could do is add the query parameter "ref=ts" to prevent the page from going switching to mobile. It helps in the browser but not the app itself.
So add ?ref=ts to the end of your app url and at least mobile users can see it in their browser.

we have created a Facebook app, but when opening this on a mobile (via Web or iPhone) the page results in a 4oh4 error. I have setup a Mobile Web URL but still (after 1 hour wait) gives a 404.
Do I need to make specific changes on my app?
Please help.
This is expected as #Igy stated. You will need to have a handler to support redirecting mobile users to your apps.facebook.com/ or you can redirect them out of Facebook to your own URL if you are going to try and link to your page directly with an app embedded as a tab.
i.e. point link to http://yoursite.com/redirector
is mobile goes to http://yoursite.com/myapp or http://apps.facebook.com/
non mobile goes to http://facebook.com//app_
Some things to note:
You won't get any page specific data back from facebook on your page (i.e. Liked or Not Liked).
Based on #1 you won't be able to restrict the non-liking app users from a page.
After trying everything under the sun to get Facebook to redirect to a mobile web URL, here is what I needed to do in order to get the redirection working:
Make sure the Facebook application is a canvas application. This gives you the ability to give the application a namespace.
Give your application a namespace so that you can access it through https://apps.facebook.com/NAMESPACE. From here, Facebook will do the detection for you, and if needed, redirect your users to your specified mobile URL.
Make sure your app is NOT in sandbox mode.
If your app is in Sandbox Mode, Facebook won't redirect you to the mobile version you have specified in your app settings.
Facebook does the redirecting for you, you don't have to. Although their version of what "mobile" is and what you deem "mobile" might be different.
I got a Facebook Page Tab App (using Timeline). It works fine in desktop version of Facebook, but when its Wall Post is clicked in Facebook App, it returns "The page you requested was not found" and forwards to an inaccessible link:
https://m.facebook.com/4oh4.php?id=282832318433409&_rdr
How come? I don't expect mobile version will be the same as desktop version, but I don't expect it reports the page cannot be found.
Page tabs apps are not supported (as of April 2012 anyway) on mobile browsers - mobile apps are, but they're not tied to the Page and need to be manually linked-to or bookmarked, the tab functionality simply doesn't exist now.
Tabs aren't supported via the app or mobile site. Best you could do is add the query parameter "ref=ts" to prevent the page from switching to mobile. It helps in the browser but not the app itself.
So add ?ref=ts to the end of your app url and at least mobile users can see it in their browser.

You can work around this problem by using a Canvas Page to redirect mobile users to a mobile site and desktop users to the page tab.
Detailed instructions here:
https://stackoverflow.com/a/15860533/121285
You can access to your app using the next link https://apps.facebook.com/YOUR-APP-ID
In this way, you can access from a desktop or a mobile with no problem
I currently have a custom app on Facebook that works fine on desktop PC's (full version of Facebook). As you would know you can't access custom apps from mobile devices and it redirects you to the wall of the page.
Is there a way to redirect them to a mobile web app if they try to access the app from a mobile device? So that way when people share links to the app I can at least show them something.
I saw the Mobile Web URL option in my app but am unsure on how this will actually work.
You are referring to the "mobile tab access" Vitrue announced this week? :)
What they are doing is this (basically):
Create a special link to the tab (mydomain.com/tablink1 or something, NOT the ?sk=app_xxxx URL in the browser bar)
On that link they have code which does a conditional redirect
If it's a regular browser/device, redirect to the tab (?sk=app_xxxx)
If it's a mobile browser/device, redirect to an alternate mobile webpage with the same content as the tab (mydomain.com/mobilecontent1)
The redirect is not on the actual tab, since the mobile browsers will never get there. It has to be on a separate page.
So if they try to access the tab on a mobile device with the regular tab URL they will not get redirected. It only works if they go to the special redirect URL. Vitrue's application publishes that special redirect URL to the Page wall.
It works very well to make sure everything you post to your Wall (which mobile users can see) does not break, but it does not really provide a redirect for mobile users trying to get to your tab.
That's the best we can do right now though, until Facebook actually comes up with a mobile tab solution (bug filed here: https://developers.facebook.com/bugs/264010470314544)
Good luck!
