I have to click retry to open Home Assistant

Configuration

Hi,

So i have this problem with android browser and windows browser, also with home assistant-docker and hass.io. Almost daily when i go to my home assistant url, it informs me “Unable to connect to Home Assistant”. As soon as i hit retry, it works.

Any idea why it is doing that?

Thanks for any tips :slight_smile:

Are you using a reverse proxy with TLS?

I had an issue on caddy where it was trying to upgrade to http/2 and this is what caused that issue. I had to add

alpn http/1.1

To prevent it trying to upgrade the connection.

Had the same issue with Caddy that @callifo describes. In case it’s helpful, here’s my a thread showing the fix: Caddyfile
