Fritz integration - not working when not using DSL

[DanielWeeber]

The problem

I recently changed from a DSL provider to DHCP as my WAN connection.
Since then the integration does not connect to the fritzbox anymore
If I enable debug logging this is the last thing I see in the logs

Hi @DanielWeeber

please provide the full logfile (it seems you already have debugging for the fritz integration enabled👍)

it seems this is an issue in the fritzconnection - to confirm this, please run the following script and provide the output.

first install the fritzconnection lib

pip install "fritzconnection[qr]==1.13.2" "xmltodict==0.13.0"

run following simple python script (fill in your IPADDRESS , USERNAME and PASSWORD)

from fritzconnection import FritzConnection
from fritzconnection.lib.fritzstatus import FritzStatus

fc = FritzConnection(address=IPADDRESS, user=USERNAME, password=PASSWORD)
fs = FritzStatus(fc)

print(f"get_default_connection_service: {fs.get_default_connection_service()}")
print(f"has_wan_enabled: {fs.has_wan_enabled}")

as mentioned in kbr/fritzconnection#218 (comment) (and following) it seems to be an issue in the Fritz!Box itself
