I've been running a LAN server using Hamachi to play Minecraft with my friends. Everything was going smoothly until today, when my friends could still see Hamachi but couldn't connect to my server. I could chat with them on Hamachi, but couldn't ping most of them, except for one friend. The Hamachi diagnostic tool suggested it was a firewall issue since it showed incoming network problems. I'm currently using Bitdefender Firewall and I've tried several solutions, but nothing worked. I'm not too savvy with networking, so I might be missing something. I even disabled both Bitdefender and Windows Firewall completely, but I'm still having no luck. Any advice?

If you’ve already tried checking the firewall rules, sometimes it helps to restart Hamachi and the server after making changes. Have you also considered checking your Minecraft server settings? There might be something else awry there.
It sounds like your firewall is blocking the traffic. You should add a rule in Bitdefender to allow the port that Minecraft uses. That might solve the issue. Just make sure the rule includes Hamachi as well, since your friends need to connect through that network.
