Login screen will not connect to server

The moment I enter my login information and click “Log In”, I am stuck for 10 minutes on a screen that is connecting and disconnecting repeatedly from the login server before booting me out, telling me that it couldn’t connect. I have tried fresh installations, bug fixes, verifying files, everything, and it will not work.

Hi. First: check your connection and firewall
If its fine, then send at least your clog file
But it will be good, if you create a report by following instructions How to create a bug report
