Hello, I ran into a small problem the other day. When my girlfriend and I want to play minecraft on a local network, I get the error given below. Also when she connects to me. We tried to disable encryption in Hamachi, disabled the firewall, cleared the DNS cache, and generally did everything that "experts" say on the Internet. We urgently need to solve this error, do the creators of the game themselves know what this error is and how to solve it? This inconvenience is too depressing.
