I do have the same problem on amd64 arch:

20-03-30 07:35:35 WARNING (MainThread) [supervisor.tasks] Watchdog found a problem with CoreDNS plugin!

Also i do experience issues with the maridb addon, which i believe is because of this.
The error there is : "Unknown MySQL server host 'core-mariadb' (-3)")

use: ha dns update --version 3

[memphisdj]

Thats what i got:

[pvizeli]

sounds like the host was not able to sync the time ntp? Or just docker hub have again an issue which is pretty oft happening at last. We need rethinking to use the docker hub soon as possible.

[memphisdj]

Its not NPT issue, i just checked and the time is correct.

[pvizeli]

Yeah, I think the issue is still happening on the docker server in your region (https://hub.docker.com/). We need still to wait until they fix the issue there. But they show also no error over https://status.docker.com/ which is weird because you log said there is a timeout between you and the docker system.

[iamBiB]

So this is a bit weird:
this is what i have in developer tools

and this is what i have in logs

Also the log file changed to
Can't create container from hassio_dns: 404 Client Error: Not Found ("No such image: homeassistant/aarch64-hassio-dns:3")
from
20-03-30 06:36:16 ERROR (MainThread) [supervisor.tasks] CoreDNS plugin is in fails state / Reset config

The time seems to be 3 hours behind on logs

[iamBiB]

logs in home-assistant.log are ok

date on the system is ok

only those logs look weird

@ibBogdan

ha dns update --version 2
ha dns update --version 3

What said the supervisor logs after that?

[memphisdj]

I finally managed to update it, first to V2 then to V3. Seems to be stable for now, will keep you posted.

[iamBiB]

seems to be working now. will keep you posted :D
thanks you
