No http/https after Mail server installation

UCS - Univention Corporate Server
#1

Dear Forum

After the MTU problem was solved the server seemed to run proper. I could install a few apps until the Mail Server App. The installation was successful but after a reboot the server is not reachable anymore via browser. I checked the logs. Apache shows:

Hey,

can you start Apache manually via systemctl start apache2.service ? Maybe it’s disabled for some reason; try running systemctl enable apache2.service so that is started during the boot process.

Additionally: what’s the output of journalctl -b -u apache2.service ?

Kind regards,
mosu
