I cannot register Plesk node in PBA-S:
Top > Service Director > Plesk Manager > Nodes > New Node
The following error appears in several minutes:
Server is temporary closed for maintenance
Port 8443 of Plesk node is not accessible from PBA-S server:
[root@pbas ~]# nmap 220.127.116.11 -p 8443 Starting Nmap 4.11 ( http://www.insecure.org/nmap/ ) at 2013-11-10 11:51 IST Interesting ports on opus-projects.com (18.104.22.168): PORT STATE SERVICE 8443/tcp filtered https-alt
Where 22.214.171.124 is IP Address of Plesk node.
Reconfigure firewall: make sure that port 8443 is accessible from PBA-S server.
