I am running into the same issue. Any help would be appreciated.

I’m presuming you have any casa ?
I had similar a few weeks back where the remote access toggle kept turning itself off and whilst I was out I had to log in to nabu casa to reconnect but it still kept doing it.
What I think worked is actually getting my son who was home at the time to open HA and turn the toggle on from there and it’s been ok since.

No i don’t have casa but thinking about it.

So how are you trying to connect ? Just with your IP have your opened ports.

Using duckdns dynamic dns service and it was working nicely until i upgrade my core to the latest version. :confused:

Ok found the problem. It was the ssl certificates expired and let’s encrypt didn’t refreshed them automatically. :man_mechanic: :love_you_gesture:

How did you fix it?

I’m having this same error now. Everything working well with DuckDNS for months until upgrading. It also appeared that my SSL certificates were not refreshed automatically. Then I uninstalled DuckDNS, deleted the certificates and reinstalled, and got new certificates. All good, and I was then able to access it via DuckDNS externally. But I can’t use the DuckDNS URL for internal access any more.

There’s a GitHub issue for this.

Having same issue. It’s NOT the ssl certificate.
