Hello, so I am trying to make Minecraft single player open to LAN work via Hamachi. I have laptop connected to internet via mobile hotspot and two Windows 10 PCs on home LAN. They are all in one hamachi network. I changed TCP/IP v4 settings metric from automatic to 1 - this seems to be necessary for the game to be visible in multiplayer menu.
From PC1 I can connect to game hosted on laptop just fine and I can connect the other way also
From PC2 I can see the game on laptop in multiplayer menu but if I try to connect I see empty world without terrain and then I get disconnected. The same happens when PC2 hosts the game and laptop tries to connect.
I don't see what is a difference between PC1 and 2 other then slightly slower CPU. Windows firewall does not seem to matter, so what can be the problem here? Seems like terrain does not load. Both windows on PC1 and 2 were installed last month...
