I installed a Fedora 6 and ISPConfig to my server, this was working properly. However, I tried to install Ubuntu 6.10 & ISPConfig later, during the installation process, there was no error. But after that, I used a PC to open the ISPConfig on my browser, I couldn't access ISPConfig because I couldn't open the web page. (https://myserver.domain.com:81) My Server is Core2 Duo 6300 with Intel 965 chipset motherboard. What happen to my server? Do you have any idea about this? Thank you!
