I am very new to UCS.
I just installed UCS 4.3 as a VirtualMachine on my QNAP-NAS, which is behind a Fritz-Box Router.
During installation i created the domain “intranet.mynas.selfhost.eu”.
(Of course “mynas” with some other input … I have the domain-name from selfhost.eu as a DynDNS.)
After installing i can reach the UCS in my LAN over the IP.
Then i opened the ports 80,443 and 587 on my Fritz-Box and activated DynDNS for “mynas.selfhost.eu”.
So UCS should be reachable over https://intranet.mynas.selfhost.eu … but it isnt
When i call the URL i get the folliwng Error in my browser:
I also tried to install Let’s Encrypt as a App … but nothing changed.
Can you help me?
… preferably in german.
