Add or Re-connect Panel Fails

[flacodirt]

Hello,

When adding server 2plesk to hosting panel group on main 1plesk, I get error below. Same when trying to re-connect.

-Servers Panel's configured using live FQDN, servers can nslookup & ping each other.
-No firewalls restricting traffic.

1plesk = Plesk 10.4.4 w/ Customer & Billing Manager
2plesk = Plesk 10.4.4

=====

Error: Connection errors:
Failed to register the panel in SSO: The following error occurred in panel '2plesk.test.com': Registration of Plesk Panel in SSO failed with errors: (1037) Can not request registration in Identity Provider: 0hp_network_getaddresses: getaddrinfo failed: No such host is known.
Please resolve the problems manually and retry to connect this panel.

=====

Note: '2plesk.test.com' is not actual one being used, it is live FQDN that works from both servers.

When I click 'Load Averages', it does display info next to the server, so its not a wrong URL/User/Pass.

Does changing hostnames or IPv6 have anything to do with this?

Thank you,

Changing the hostname was the issue.
