Custom map hosting issue

Hello! I’m having a major issue when trying to play custom games in Warcraft 3 Reforged via Battle.net.

When I host a custom game, I cannot see the players joining my lobby, even though they are actually there. Additionally, I cannot change player colors, close slots, or interact with any lobby settings — nothing works at all. After a short while, I just get kicked out of the lobby.

A similar issue happens when I join someone else’s custom game: I can’t see the nicknames of other players in the lobby, and then I get disconnected from it. However, this doesn’t happen every single time — occasionally, everything works fine.

This issue started happening recently. Before that, everything was working perfectly. I would really appreciate any help in resolving this problem!
