Online multiplayer game via Hamachi on a random map.

Hello! I have a question about playing online via Hamachi on random maps. My friend and I decided to play on a random map. I created a map in the game, then copied it from the maps folder and sent it to my friend, who placed it in the same folder. As a result, when he connects to me, an error 0.5.0 appears.
What am I doing wrong? Or does anyone know how to play on random maps and can help me figure it out?
