After one successfull login at the next login attempt the screen flickers like crazy and on top a yellow bar with conncting flickers like heck.

Can you see any outstanding messages on logs?  
You can increase the verbosity of the logs in Admin \> Logs

this is probably another deployment config. Check also if you can see any connection errors from the browser to the server (developer tools \> network)

Hey after some fiddeling around i found the issue.

As im Using Unraid and Rocketchat in an Docker i added the Variable:

USE\_NATIVE\_OPLOG = true

This was mainly to get rid of the error:

Change Stream is available for your installation, give admin permissions to your database user to use this improved version.

But with this fix installed, i get the Problem as above shown.

So thanks for the help. 🙂
