Every time that me and my friends have 3 to 4 players when we start combat 1 or 2 of us are getting kicked from the game. I personally have uninstalled and reinstalled both the game and steam along with validating the files. The game runs perfectly when i play by myself.
If the clients are using the Companion, get them to not use it. The companion is very unstable within Multiplayer for Clients.
I’m the one thats been using the companion, but im not the one hosting the game.
Try and play without using the Companion and see if that makes any differences for disconnections. If it doesnt then im not entirely sure what the issue could be as MP has been quite buggy since Companion Update in July.
