When in Customer Panel I go
Sitebuilder > Host New Parallels Plesk Sitebuilder Site and fill in a domain name I get
Server is temporarily closed for maintenance
At the same time in OBAS client httpd log /var/log/httpd/hspc_frontend_error_log there are messages like:
Tue Feb 24 12:00:45 2015] [error] [client 184.108.40.206] (20014)Internal error: proxy: error reading status line from remote server 127.0.0.1, referer: https://admin.server.com/cp/index.cgi/system/sb/act,new/zone,system [Tue Feb 24 12:00:45 2015] [error] [client 220.127.116.11] proxy: Error reading from remote server returned by /cp/index.cgi/site/sbnew_process/zone,system, referer: https://admin.server.com/cp/index.cgi/system/sb/act,new/zone,system
Such behaviour is caused by the software issue PBAS-29862 and was fixed in OBAS 4.5.4 release.
Upgrade to 4.5.4 as described in How to upgrade PBA-S system to the latest available version.
If upgrade is not an option for you, there is a hotfix for 4.5.3 version.
The hotfix consists in reinstallation of four RPM packages, please find them attached (32-bit versions):
To apply the hotfix please run
# rpm -Uhv hspc-skin-panel-theme-4.5.3-46.swsoft.i386.rpm hspc-cp-sbsite-4.5.3-46.swsoft.i386.rpm hspc-root-4.5.3-46.swsoft.i386.rpm perllib-4.5.3-46.swsoft.i386.rpm # service hspcd restart
