I am running a bungeecord network and recently I have been having issues with joining.

I open minecraft and go to multiplayer and join my server. It gives me the logging in message for about 5 seconds then says 'Connection Lost: Disconnected'

In order for me to be able to join, I refresh my server list and wait 5 seconds.

It then lets me join but immediately tells me you logged in from another location. (sometimes) I then join again and it finally works.

I have a video being uploaded to youtube and I will comment the URL for further proof.
