DuckDNS - Failed to update external IP. Should it update?

Having done some electrical work in my house today my connection to my Internet provider was reset. As such they must have give me a new IP.

When I tried to connect to HA I couldn’t. Checking DuckDNS I could see the IP was now out of date.

Back in HA I restarted the DuckDNS add on and the logs said the cert was OK. Trying to access i still couldn’t using DuckDNS.

This happened last month but I thought it was me fiddling with HA to be honest.

I thought DuckDNS updated the ipaddress when it did a cert check? Could I have a configuration issue?

Anyone have any ideas. It’s happened again today and as such were locked out.

The logs are tell me it’s all fine?
