"Unexpected Error" when adding integration

[chrisstrug]

Hello.

I have three Tapo 110 smart plugs. I had previously successfully added one of them as a device via the integration (great work btw!). I've rebuilt my HA install as a docker container on a RPi4, however when I attempt to add any of the plugs I get a failure with an unexpected error message. Going back to my old HA install my old plug is showing Error communication with API:

This is definitely not the username case issue (tp-link username is all lower case and previously worked).

Question - does the integration have any logs that might give me a clue as to what is going on?

Thanks.
