Joined UCS Domain, but can't do anything

I joined my Fedora 32 to Univention domain via the “realm join” command. It worked and I can see the laptop is showing as a computer in Univention. I tried to log in as one of the domain users on the Fedora 32, but it keeps barking at me stating “Sorry that didn’t work. Please try again”.

Also, I thought that after joining the machine to the domain, I would be able to use its hostname instead of ip address when accessing remotely. In my case, it is not working. Even Univention couldn’t resolve the IP of the laptop.

I disabled SELinux on the Fedora and I am still getting the same results.

Any ideas?
