Newbie needs help! HA cannot reach beyond LAN

Looks like the dns container is failing. What hardware are you running on?

Most of what has been written here is way over my head.

However looking at my HA set up

The dns is pointing at my router - the router sorts out talking to real name servers.

Worth a try?

Thanks, set it to 10.0.1.1 but still no joy

[steve_jo]

the dig output shows 127.0.0.11 is unreachable.

Quick google tells me that address is the internal Docker address used for DNS by HA.

There’s something messed up with your HA installation - sorry no idea how to fix. I’d try a reinstall…

Good luck

Seem to be a few similar issue on the forum, e.g

Unable to connect to any external services

Since updating to 0.81.6 all of my external services have stopped working. Hive component will not connect to the Hive servers Trying to update Hass.io to 0.82.0 (the offered version) fails without an error message (it tries for a while then the update button briefly flashes red) Connecting to the HA Cloud was stuck at “connecting”. I tried logging in again but now it just says, “Unable to reach the Home Assistant cloud.” Trying to add an add-on from the add-on store fails without an error m…

Maybe a few more things to try, sorry I can’t help further.

Thanks, that is really helpful!
I don’t have too many devices or integrations established into HA yet, so I think a re-install is worth doing…

Glad you’ve taken the time to help so far thank you!
I tried the suggested “hack” but to no avail.

[steve_jo]

Couple of things…

If you do a backup you can restore it later so you don’t have to lose anything. See about the networking first though!

Have you tried
ha resolution info
to see if it finds anything

I’d maybe try a linux on a stick OS on your NUC - just to check if that can see the outside world - it would eliminate some weird fault with the hardware.

and finally…
ha dns reset
Does that change anything? Do your logs still show the memory error?

Let us know when you find a solution

[cozza]

OK, so just finished doing a full re-install…lo and behold all is good!!
Right from the go I am able to see the outside world and finally enable HA Cloud. No fettling of IP, DNS or port settings

Thanks @steve_jo, @aceindy, @nickrout and @francisp for your quick and helpful advice!

Hopefully, the help you’ve provided here may help someone else with a similar problem…
