My current guess is that my reverse proxy authelia is in front of it and seeing the character is "<" I'm thinking that the response the app gets is a html page from cloudflare or authelia saying it's not authed properly, but this doesn't happen on the browser extensions.
If I was to fix this, I would like to have debug info on what call is being made while I login, and if the response data is a webpage with an auth error then say that.

I will do some testing on my side but that's my current thoughts as the browser extensions and deskop apps work just fine with the self hosted server.

Confirmed it was Authelia which I changed policy to bypass for. Ideally there would be a way to handle reverse proxy authentication and redirecting to the browser for login or something.

As this was resolved with Authelia configuration, I will close this. Please let us know if you have any other issues.
