I also have Relayed with everyone on every Hamachi server I am connected to. I have tried so many solutions, none of them have worked.
I have tried:
Disabling my computer's firewall entirely
Allowing hamachi through my firewall
Port forwarding
Restarting the Hamachi service (too many times)
Reinstalling Hamachi
Inputting Local TCP and UDP addresses (and portforwarding them, then restarting hamachi)
Restarting my router
Restarting my computer
A bunch of other stuff that hasn't worked.
Also noted is that it randomly started working yesterday well after I had given up with attempting to fix it. (although it has since ceased to function again)
I've noticed that on the Connection : via relay details... screen, the address part for Server shows N/A. I wonder if this has anything to do with the problem.
Please help.
