Technical issues with Heroes III.

The problem arose in multiplayer with 3 or more players. We connect to the server normally, but in the in-game chat, even before the game starts, the player clients cannot see each other (only the server sees messages from everyone; the other clients only see the server). The game starts normally, but when a client skips their turn for the next client, the data is not sent, and the turn does not pass. The problem started after patching SoD to Hota. Both versions have the HD mod installed. In SoD, everything works perfectly; in Hota, it doesn't. Perhaps someone has encountered this problem, or maybe it can be fixed somehow. Hota version 1.4.2; we tried using a regular LAN connection without Hamachi or other third-party programs (it's definitely not related to them). Summary: clients in multiplayer do not ping each other (if there are more than 2 players; a 1 vs 1 game plays normally).
