[snitun.client.connector] Can't connect to endpoint

Today all of sudden, my HA stopped communicating with NabuCasa.
NabuCasa integration in HA shows I’m connected to NC.
Mobile notifications arriving my phone. HA works in local network.

The only thing which does not work is access from outside, through NabuCasa.

logs are full of errors like this:

ERROR (MainThread) [snitun.client.connector] Can't connect to endpoint

Is this something known?


Got the same error and logged issue with Nabu Casa
Can’t connect to endpoint

I’m getting the same error, when I try to update HA Core.
I’m currently at 2022.12.4 and trying to update to 2022.12.8.
