like i say in the topic what can i do ? google search in the end comes to reinstalling zerotier which i did but it doesnt solve the problem…is it definately ISP related ?
also something else that is strabge:
nslookup planet.zerotier.com
Server: 1.1.1.1
Address: 1.1.1.1#53
Non-authoritative answer:
*** Can’t find planet.zerotier.com: No answer
internet access and dns resolution works flawlessly for any other domain
