I’m having problems renewing my cert of letsencrypt. I have both port 80 and 443 open and pointing at my HASS.
This is what I get:
> The standalone specific supported challenges flag is deprecated. Please use the --preferred-challenges flag instead.
> Saving debug log to /var/log/letsencrypt/letsencrypt.log

You have something already listening on port 80. You can find that by running sudo -pant|grep ":80 "

Oh yes thanks. I had Pi Hole running and listening on port 80 for the web interface.
