Hey there,

I just had a similar problem, but unrelated to your webbridge packet.

Can you please confirm that your raspi has a solid network connection? I had the problem with the "Publisher already registered" in my ubuntu 20.04 machine where my network card was suddenly not connected anymore. After setting / fixing my network, everything was back to normal.

Also this 'NoneType' Error suggests, that new_len has not a type because the request for the IP address failed, as you also have a networking issue..

Just a guess into the blue, but maybe it helps..! :)

Cheers
