new install Deb/ISPC3 can't use FQDN
I ran a Fedora system for about a year with ISPConfig3 but I wanted to switch to Debian so yesterday I installed
Everything appeared to be alright. I after installing Squirrelmail I could navigate to FQDN (e.g. server1.example.com) with FQDN/webmail.
After installing and configuring ISPConfig3 I could navigate to FQDN:8080 and get to the control panel.
But running out of time for that day and because my server wasn't setup yet, I powered off for the night. Today I power back on but I can't do anything with FQDN, but only can use my local IP address. Everything is accessible with local IP address, but FQDN goes nowhere.
What could be wrong? /etc/hosts looks right, but of course it would because it worked last night.
Any help would be appreciated. Thank you.
