Sonos failing to connect - unverified player

I had to remove my Sonos devices from ST a few weeks ago. When I tried to connect them back I get the repeating error in the logs at the bottom (this log is with just one Sonos device on my Wifi for simplicity)

Support suggested resetting Sonos multiple times and eventually it may work. This seems like they don’t really understand this issue but maybe their users have vaguely reported something along these lines working.

Can any one please suggest a better and clearer method for getting these devices readded? I’ve tried the rather vague method of resetting sonos a few times and unplugging the hub and changing the ip of the sonos on my router several times and no luck so far.
