Heres a solution, if you are using wifi, turn off data connection of your phone on yor cellular settings then try restart chat. If you are using 4g turn off the wifi. There is a conflict on data connection if both wifi and data connection is on
I have Facebook turned off. My intention is to use Messenger across phone, PC, and tablet. This is all on Microsoft!Well... worked for one week... Now reverted back to "can't log in to chat". Apparently MS is aware of this but states that this is a problem on facebook's end.
But us users still can't use on of the key selling points - FB chat integration on WP!!
From MSFT:
[INFO]Many users have reported issues with signing in and receiving Facebook messages in Windows 8 messaging app, Windows Phone messaging hub, and Outlook.com. We are actively working with Facebook to resolve the issue. Other contacts (e.g. Skype) should not be affected.[/INFO]
Yes i am also getting this error from many days. I have never felt easy chatting on facebook for this phone.
Have my Lumia 925 with the latest build about a week now and ive tested and tried everything! new fb account, complete reset and all other tipps from wp central and dem Microsoft community and it has NEVER been worked. the Chat is always offline - coulndt connect to Chat!
I was also having the same problem, could not connect to FB chat. I had tried everything, unlink FB account from MS account, change passwords, change settings but nothing worked.
FB chat worked - sort off - until a couple weeks ago.
I've read on answers.microsoft.com a user suggesting the uninstall of Skype, so in desperation I uninstalled and can you believe it? FB chat can now connect and seems to work.
So if you're having problems connecting to FB chat and have Skype installed, try removing it (does not seem to resolve problems with message lag and other problems).
