It looks like your SSL cert needs renewing. I use certbot to auto-renew every 3 months or so.

@retoor NIce, didn't know caddy. But the workflow is pretty much the same with certbot. At least with the nginx plugin.

Add new subdomain, run certbot --nginx and it gets a cert.

Guten Morgen!

@retoor And you know have my login and password, because I use it, too. Keep my name a secret, okay?

I use Traefik, but yea there's Caddy and there are even Lua scripts for nginx that handle LetsEncrypt.

It looks like devrant is using LetsEncrypt, so whatever renews the cert must have just thrown up. I've had a misconfiguration Traefik that couldn't get certs on one of my sites for a while.
