I have Ubuntu set up as a plex media server for many months now, yesterday after installing Samba, I now can't connect to any port using my other machines in the same network. From my windows machine, when I ping the the ip 192.169.100.77 it reaches but when I try to connect to 192.168.100.77:32400 or whichever ten ports for various things I have, it suddenly won't let me connect.
