I have hamachi installed on three pc's (2 with win 10 and one with win 7). Everything was great till few days ago when hamachi can't help me to play with my friends. When I ping every pc from those 3 from other I get the message requested timed out. I use hamachi since beggining and I didn't have a problem that I can't resolve till now.
See if your friends can ping you, it could either be a firewall has decided to block Hamachi. Start by whitelisting Hamachi on your local firewall and if that does not work try doing it to your network firewall if there is one.
They can't ping me neither. We all havemicrosoft essential security and all it work fine till now. I put hamachi-2-ui in excluded list but still don't work. Can you help me please and tell me whats should I do step by step?
