Hi @bru no ,
I understand that you are trying to activate Azure arc on a server but you are getting the error "AZCM0066: Unable to Obtain Agent Status error".
This generally happens when "localhost" is resolved to the "::1" address which is the IP v6 loopback address.
If you are not using IPv6 as a server then you should edit the /etc/hosts file and remove the entry "::1 localhost" then it resolves the error.
