Home Assistant Tado Intergration Error

Hi all,

I’ve a issue which I can’t figure out why it is happening.

For several weeks I had my Tado thermostat intergration working fine and all of a sudden it stopped working. I deleted the intergration and tried to reconfigure but I get an error after entering my credentials.

When I look in the log I see the below:

Unexpected exception

Looks like it is refusing connection over port 443. I do have port 443 forwarded to the same host machine where HA is running on (docker container HA core).

It was working before, nothing changed…

Any ideas?

i have the same problem how did you solve it ?

I had pihole running on the same host (ubuntu) so I had to disable the host system DNS resolver.

I am running home assistant in vmware. I did not change anything ? I dont know what happend

Reboot of HA and/or host machine?

Did both, restart host system multiple times and the supervisor.

Are you sure the host machine has access to the internet?

Yes because i am now not at home and can connect over the ios ap or with the browser :slight_smile:

@darryl12123 , how did you disable the host system DNS resolver
