Hello, me and my friend tried to play aoe 2 de. My friend wanted to join my lan server, but when he searched for LAN server in game, he couldn’t find it. I tried to invite him through Xbox app in game, but it did not want to load itself. It worked perfectly fine on multiplayer, I could invite him with Xbox app. We want to play LAN cuz our internet is ■■■■■■. We both own AoE 2 DE on Microsoft store.
Check your Windows security settings. I haven’t figured out the rules needed yet but if you go to the firewall settings and disable the firewall for the active network (usually domain or private) that solved the problem for us.
