I have been using Playit for 8 months with zero issues, and today it began to give people on external networks either the getsockopt or unknown host error. I have not changed networks and neither have they. One of them can join from his laptop but not his PC on the exact same network. Using the URL or IP does not make a difference. My DNS is set correctly and my Firewall already has an opening for port 25565. Any help would be greatly appreciated. Thanks!
