Instant disconnect from online custom game

Hello, I purchased warcraft 3 reforged, I’m trying to join a custom online game but I’m having huge problems with it. I connect to a created game, I’m in a lobby, I wait for the lobby to fill up, the game starts and after the game loads, it shows me the map for a second and kicks me out of the game with the console saying I’ve disconnected from the game and pops up the game stats (results) like the game is finished… this happens to me in 95% of all created rooms where I connect and want to play, it just kicks me out right after the game starts. It’s not the internet, I’ve tried 3 different internet connections.
I’m connecting to a room with a ping of 35-40, that’s Ok
Can anyone help me? I’m so unhappy that I can’t play custom online games at all
