New Pleskian
I wonder if someone might be able to shed some light on this for me. Running PLESK 9.5.5 and Win Svr 2008 (Therefore cannot ask Parallels support as its an EOL combo).
PLESK is running a shared hosting server, around 22 IPs on it. A maintenance task was to remove any unused IPs from the panel. IP Addresses section, find any at '0' client usage and remove them. One server in particular presented the list of the remaining 21 IPs with nice red icons next to them, quite rightly frightening the person removing the IP from this server. Clicking RELOAD on the PLESK panel put the IPs to a green status.
All was apparently fine, websites still loading, email etc. Some time later we noted our monitoring software showed this server as DOWN. We also noted that PBAs showed this server as 'Unavailable'.
Why would removing an unused IP, a) make the whole list of IPs go red, and b) when 'reload'ing the IPs via the PLESK panel, would this then result in PBAs and other tools wanting to connect on specific ports, not work?
We've checked the adapter setups, firewalls, restarted services, etc all to no avail, and are a little stumped now... any thoughts?
The PLESK panel will load via an internet browser, connecting via the external network (office ADSL) on 8443, yet, a telnet from the PBAs server on our internal network, will not connect to 8443 on that one server (we can telnet to other shared servers on port 8443).
EDIT:::
Resolved this ourselves. In case anyone else encounters this, the problem stemmed from an IP address on the server lower than the servers own IP. Removal of this IP resolved the problem.
