When I try to visit my website at https://www.mydomain.com:81 I never get a response. ISPConfig is running in the background. When I try and set something else to listen on that port (ie. Setup my main apache to listen on port 81) it tells me the port is already being used. Here is my output from netstat -a |grep 81 Code: netstat -a |grep 81 tcp 0 0 *:81 *:* LISTEN unix 2 [ ACC ] STREAM LISTENING 80181 private/error unix 2 [ ] DGRAM 83081 Here is my output from ps aux: Code: root 28231 0.0 3.0 12268 7728 ?

Please let me know if there is anything else I can provide to help figure this out. Thanks, Fred
What does netstat -tap show which process is running on port 81? Have you tried restarting ispconfig_httpd? Does a wget / curl / lynx https://localhost:81 work? Can you see anything in the ISPConfig's apache error / access logs?
Please post the output of the following command too: iptables -L I guess you blocked port 81 with a firewall.
