uvok, 
Uhhhh? What?
I just set up #caddy as a reverse proxy for dendrite.
Mainly for automatic certificates.
I forgot to do ufw allow port 80 (or the equivalent), only allowing port 443.
And yet I got the certificate from #letsencrypt...
Reading the locks, the "tls-alpn-01" challenge was used? What's that? Never heard of it before.
