    Finally found out why I couldn’t renew my Let’s Encrypt cert.

    Did you know fresh installs of Debian Testing come with firewalld installed and enabled to auto-block all incoming connections? Me neither!

      Oh yeah. Docker too. Can’t spawn a docker container and don’t know why? Yeah, you need to make a firewall exception so that the virtual system running on your system can see itself. Yeah.
