Home Assistant can't access the internet but Hass.io can

Installation Home Assistant OS
1

So first a bit of history, I’ve run HassIO on this Pi3 since the model was released, same network, cable is good etc. I’m reinstalling as the SD card failed. on both 2.11 and the just released 2.12 Home Assistant has struggled with internet access, HassIO does have internet, I can install new addons etc and HassIO logs show multiple happy connections to the internet and if I install the SSH add-on then I can ping without issue, however HA itself cannot seem to resolve and I get errors like the below (these are from a brand new clean install).

In my head this seems to be something to do with the container but I’m not sure how to start fault finding on it, I’ve seen things that kind of look similar on the forums but mainly from people who’ve had PiHole installed which I don’t.

Anyone have any ideas?

Home Assistant Log, default config fails to connect to weather service, all other online API attempts (e.g. Nest) added after this fail.

Never worked with containers, so idk if it’s some VM issue.
But, are you sure your HA instances have correct network settings?
I spent a couple of days wondering what was going on, and i had it fed with the wrong gateway address.
(just a thought:))

I had a problem within the docker instance on my hassio where home assistant also lost its ability to connect to the internet as well. I don’t remember the exact fix but I believe I had to manually specify the dns servers to use in the docker level configuration. I had to ssh into the hassio instance (not ssh add-on) to manually edit a config file. After rebooting home assistant was able to connect again.

I’ve gone back to Hassbian for the moment, a little frustrating but there’s nothing special about my network etc and tried another pi to be sure so have had to leave it for now. Hassbian gives me sensible control over the host OS and not being that familiar with Docker etc it was easier for now.
