and if y click in retry appear this:

this is the error:

Logger: aiohttp.server

  File "aiohttp\_http_parser.pyx", line 523, in aiohttp._http_parser.HttpParser.feed_data

But if I do the config from the configuration.yaml like this:

But it doesn´t work. it show the error I upload in the first comment. I´m 100% that my port 443 is open and linked to the ip of my HA

I have the same problem. did you find a solution?
