@Dzoker2 this looks like someone is attempting https, when the other side is expecting normal http. Is your homeassistant reachable from outside?

It is not accessible from outside... I do have an add-on HTTPS Everywhere - https://www.eff.org/https-everywhere in Firefox... could that be the issue? I access my HA via Firefox.

It will most likely be your browser attempting to access the resource with https while it doesn't have the setting to handle SSL

I have same version and same problem, when trying to login through a nginx proxy manger "reverse proxy" running on the same docker-installation.

It's driving me nuts, because I can't get remote functionality to work at all (only if I login through OpenVPN against the http-address). In Chrome I only get to the part where the "Blue House" shows up - and end up getting "Unable to connect to Home Assistant"... I have a theory, that it could be due to docker running as host - and the docker-nginx (reverse proxy) can't access the hameassistant docker-machine for some lame reason..

This is from my log:

It would be great, if a developer could extend the functionality in the log, to say which endpoint the installation is trying to reach, when the exception occur.

I have deleted the extension from Firefox so it is not forcing https anymore but I still get that error in the logs. anything else I could do to troubleshoot this?

Same issue here. I am very new to all this but willing to help. I currently have a very basic setup using a HA green. Someone mentioned http vs https above and I am using Duck DNS, so could that be the issue? If so, I really dont know enough to try and resolve that while still being able to access my HAOS from outside my network.

[Dzoker2]

Hi All, It looks like this error stopped after I removed the https://www.eff.org/https-everywhere extension from Firefox. will keep an eye on it.
