My TE is working fine today.
I'm seeing this problem with my TE and TT after about 2 minutes of play time doesn't matter if I'm on station or in sector idle or doing something, the game stops chatting with the server. I can walk thru the station or warp around in a sector but chat stops, guild menu is blank and map screen if undocking or gating. Same computer same log in check marks on game panel I can logged in my PS and have no problems.
That tells me it's not:
Internet Service Provider
Router
Computer
Game setup
Something about my Terrans and chatting back and forth with the server.
Hopefully that will help.
