1. The problem I’m having:
I wanted to try and host a static site on my caddy web server. I’m running caddy through docker compose and have added my site directory in the same directory as my compose.yml. I added the ./site:/var/www/html directive in volumes to mount the site to the internal storage. Now, when I try to open the caddy server it responds with either a 404 error on the 80 port or a 308 error on my FQDN.
2. Error messages and/or full log output:
* Trying 192.168.5.102:80...
* Connected to 192.168.5.102 (192.168.5.102) port 80

3. Caddy version:
2.9.1
