I'm in the same boatYep, tried the IP and also tried using the raspberrypi.local address and got the same.
I’ll see if I can find the logs, couldn’t see any similar issues listed, I do wonder though if the Pi 0 is up to the job, think it’s supposed to be 3+ as a minimum
0 w and not able to log on, the IP address for the docker seems to be 172.*.*.* So maybe that's causing it?
