Same here. We have paid service subscribed. Problems started at friday, and persist until today and still going. Users can't get to server resources and SQL databases because relays are not working. Every client and servers on hamachi network are red, and some of them blue. Give us some kind of feedback!
Diagnostic tool returns "Tunnel is currently blocked" for every connected client to hamachi vpn. Your servers are not relaying connections properly for 4 days!
