Disconnecting from Multiplayer every turn

[MCR2601]

When trying to play Multiplayer and there are more than 2 people (me + host) total in the game, it disconnects me from the game when we end a turn.
I tried to deactivate my firewall, reinstalling the game and deinstalling Hamachi.
Ingame, it is only shown that I lost connection to other players, but not the host. For everybody else i leave.
The "Please wait" label in the bottom right corner stays forever.

Somebody have any ideas?

Were do you live? what is your internet speed/latency like? Civ6 has been pretty stable for everyone to date.

I live in Vienna, Austria. On speedtest.net i got an 8 ms ping to the nearest Server with a download of 9.2 Mbps and Upload of 0.74.
The Civ5 Multiplayer worked flawless.
My Game is able to join the game and i can see the map, but when the turn processes it kicks me out. Civ then still thinks the host is still here but i cant do anything.
Is there some kind of log for multiplayer where i can find information about what happened?

I did some more research and found other people with the same problem. They think it has to do with the router.
Do you have any idea what routersettings can block civ6 but not civ5?
