I just tried to configure TR064 binding under OH3.
With klick on add thing in inbox and choosing tr064 I got 3 new things shown for manual adding (Auto-Discovery don’t work for me):
- tr064:fritzbox (Bridge)
- tr064:generic (Bridge)
- tr064:subdevice
After choosing tr064 Fritzbox I configured host, user and password and add the thing.
The thing is created by openhab, but directly got stuck with the following error:
COMMUNICATION_ERROR
java.util.concurrent.ExecutionException: java.net.UnknownHostException: fritz.box: Name or service not known
Because on same machine openhab is running (Dell Server with Ubuntu 20.04.1 LTS) there is a fully working bind-server too, fritz.box not resolveable.
So in my opinion problem is, the TR064 allways using fritz.box as domain instead of configured IP 
Can anyone confirm this?
Edit further informations:
After create entry in /etc/hosts with fritz.box and IP, I can see openhab logging in to fritzbox in Fritzboxs Logs. So really looks like binding always uses domain instead of IP.
Now I got error:
COMMUNICATION_ERROR
java.util.concurrent.TimeoutException: Total timeout 2000 ms elapsed
UPDATE:
I turned on DEBUG in karaf.
Now every Minute I go a debug entry in log:
2021-03-16 20:43:32.233 [DEBUG] [ding.tr064.internal.Tr064RootHandler] - endpointBaseURL is now 'https://192.168.10.XXX:49443'
But that’s all. Bridge still showing COMMUNICATION_ERROR
java.util.concurrent.TimeoutException: Total timeout 2000 ms elapsed
In logs of Fritzbox
Anmeldung einer App des Benutzers BENUTZER von IP Adresse OH-SERVER-IP
Firewall looks fine, no drops found. And didn’t changed since tr064 worked under OH 2.51
Here the logs from Support Information of Fritzbox, returning every 1 minute
