Unexpected error while logging in using Facebook connection with the "Oops!, something went wrong" message

[iyadshami]

hi,
some of our customers experienced an error when they logged in using Facebook connection, the expanded error message is:
" You may have pressed the back button, refreshed during login, opened too many login dialogs, or there is some issue with cookies, since we couldn’t find your session. Try logging in again from the application and if the …"

It is strange thing that this error has just started to show today, we have not altered our app or connection configuration recently, except adding a testing logout URL to Allowed Logout URLs.
can you help in debugging the source of this error.

this.auth0 = new Auth0.WebAuth({
      domain: '***.eu.auth0.com',
      clientID: '***',
      redirectUri: 'https://***/callback',
      audience: 'https://***/api',
      responseType: 'token id_token',
      scope: 'openid profile email full_access'
    })

does this answer has to do with the Error we are experiencing:

Auth0 error page after the first Facebook login attempt

Hi everyone. I’ve been investigating this issue and I believe it’s caused by a behavior in Facebook’s login page which ends up making two consecutive requests to Auth0’s callback URL (e.g. https://yourtenant.auth0.com/login/callback) under certain circumstances. As you know, Auth0 acts as a client application for Facebook, in a separate OAuth2 conversation that happens when the user clicks on Facebook as the desired authentication method. The user was not logged in before The timing is just …

The issued you linked to was supposedly fixed by Facebook already, so I don’t expect that to be a problem.

If you can reproduce the issue on your side, please record and attach a .HAR file to provide more clues when troubleshooting.

Hi

Started seeing similar issue too. Only with facebook and so far only seen this happen on android mobile. Works from from various browsers on Windows asp.net app using universal login.

Bumpy bump, anyone got any ideas. Really stumped as facebook works fine from browser, but ion android on auth the installed fb app is invoked and I assume it’s sending an incorrect or changed request back to auth0. I’m not a android dev so limited on knowledge on how to trace what could be happening.

As you commented on my own ticket, I have the same annoying problem. Still looking for a solution if you happen to find something on your side. Thanks.

It is not possible to get the HAR file right away I have been trying to get it for 6 days but our customers are located in different areas therefore it is really difficult to get it.
Facebook-connection is the primary login method to our service and we started losing customers because of this error.

A little googling and I think what’s happening is facebook on android has registered the fb app to handle fb urls hence the fb app is invoked during the oauth flow and then throws a wobbly. I’ve changed the fb app settings on a test android phone under “set as default” “Go to supported URLs” from “In this app” to “in other app” and I can auth okay using fb.

So question is

We have made a short video for our clients to exactly do that,
We are waiting for any information from auth0 team about this problem
