I've set up ISPConfig following the manual without issue at least a half dozen times. However, this time on Ubuntu 14.04 + Apache I get a 500 Server Error on my initial site that is set to PHP5-FPM (FastCGI works). This hasn't been a problem on prior setups and I'm not sure where else to look. PHP5-FPM services appear to be running but the 500 persists and I don't see PHP5-FPM when listing processes (top) on the CLI like my other active PHP5-FPM servers. This new ISPConfig Server's first site error log appears below. [Wed Nov 05 23:22:08.705535 2014] [fastcgi:error] [pid 26064] (111)Connection refused: [client XXX.XXX.XXX.XX:35885] FastCGI: failed to connect to server "/var/www/clients/client1/web1/cgi-bin/php5-fcgi-*-80-somedomain.org": connect() failed [Wed Nov 05 23:22:08.705663 2014] [fastcgi:error] [pid 26064] [client XXX.XXX.XXX.XXX:35885] FastCGI: incomplete headers (0 bytes) received from server "/var/www/clients/client1/web1/cgi-bin/php5-fcgi-*-80-somedomain.org" Any ideas where else to look/check?
