Can not renew a cert with certbot: Timeout during connect (likely firewall problem)

Hi @linuxnutt

there is a check of your domain, ~3 hours old - https://check-your-website.server-daten.de/?q=nutthause.com

Your https works, your port 80 doesn't answer:

Only timeouts.

You have a lot of older certificates, startet 2017-02-03 23:27:00. Perhaps you have used tls-sni-01 validation / port 443, that's not longer supported, support ended ~2019-03-15, looks like you have created your last certificate via tls-sni-01 validation.

So it's impossible to check your configuration. Please open your firewall, then recheck your domain.
