Hassio-dns crashing over and over

Installation Home Assistant OS
1

Not sure if it is a coincidence or not, but updated to 2022.3.0b5 from 2022.3.0b4. Supervisor also updated to 2022.02.0 and suddenly hassio-dns keeps on crashing. I have tried

ha supervisor repair

ha dns restart

ha dns restore

Same issue… logs are empty

Same problem here!

I noticed scripts I created that use dns within the home assistant docker image has stopped working. Did some digging and found that hassio_dns is restarting over and over again. I hadn’t updated home assistant core in months. It looks like supervisor updated itself recently because it’s showing version 2022.02.0. I’m guessing this is the cause of the problem.

Here’s the supervisor log:

22-03-01 23:50:49 WARNING (MainThread) [supervisor.misc.tasks] Watchdog found a problem with CoreDNS plugin!

Hi,

I had the same problem, but downgrading the dns seems the fix the problem.
I ran the following command:
ha dns downgrade

Same issue here, trying to downgrade but it only gives me a notice about 2022.02 is already in use

5

I uninstalled apparmor on the host server and everything is running again after a reboot
Perhaps this was a sign that is is time for me to move over to a supported OS :slight_smile:

I assume it will break again when the supervisor checks for an update… Anyways via https://github.com/home-assistant/supervisor/issues/3475 I discovered that Ubuntu wasnt supported. Only Debian is. I moved to that and the problem was solved for me

jumping in late, new user to HA installed in virtualbox using ubuntu 64bit few weeks ago. i am experiencing sporadic crashing of the HA core in the VM. after reading through these threads is it suggested I do a new install using debian vs. ubuntu in the VM?

If you are using Ubuntu try to adapt the following (based on Debian) for your setup. Instead of using VirtualBox, use KVM which is native to Linux virtualisation.
