Facebook OAuth Login stopped working

Question

In my website I use oauth for login via google, twitter and facebook. Since 24 hours I noticed that the facebook login does not work anymore. I get the following error message when I try to log in:

"Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings."

I am not using https but http.

Can anybody please shed some light on this new situation? Thanks.

Answer 1

Just ran into this as well. Looks like Facebook started enforcing strict mode for redirect URIs this month. Resolution is to enter in your auth callback URL in the "Valid OAuth redirect URIs" field.

Look at Step 3 at this site: https://auth0.com/docs/connections/social/facebook

Answer 2

Double check your "Valid OAuth redirect URIs". All of URLs must be set where exact as you use it (with GET params)!

For example, if you redirect URL is http://somesite.com/auth?type=facebook you cannot set just http://somesite.com/auth from now.

TIP: You can find this URL as a param in page address where you see an error message.

Answer 3

In march 2018, facebook change Oauth url, https://developers.facebook.com/blog/post/2017/12/18/strict-uri-matching/. I use Hwioauth bundle, just solved the problem. Make sure you add all Valid OAuth redirect URIs. In my app has http://localhost:8000/

http://localhost:8000/connect/check-facebook

http://localhost:8000/connect/facebook

Answer 4

I got the same problem with the same symptoms where the callback URL on logon pop-up with some weird app_id.

Finally, after a lot of search (rare case), I found that which caused by the conflict between Manychat Script and FB login button. (the weird app_id on pop-up comes from Many Chat).

It's just a tips for your search, I'm not sure our problem caused from the same issue.

Hope that help. Bryan
