I'd like to bring together some information about network related stuff after the Beyond update to get some things sorted out.

What I know so far: Galaxy is needed for network stuff. Check. (I don't use the beta btw). I'm on Win7 where special microsoft update stuff has to be done to have a functional discovery network connection (this TLS 1.x thing). Check. When started with galaxy there is an option to join or start game. Check.

Multiplayer: I can't any see any other games in the multiplayer lobby any more. It worked with 1.77_mp. (EDIT: Wait... or was it to select a savegame in this menue first? In this case I can't select a savegame / can't create a new in multiplqayer)
Nexus: Works for me. I see lots of people hanging arround there. Chat works etc.
Discoveries Network: I have connection (green light) non stop since two or three days after the update.

Is anyone able to join other games since 2.0x?

UPDATE: Meanwhile I think it's not a bug but a feature... You can easily go to the Nexus and join up with others there. So maybe they have taken out the previous MP-start...?
