Caddy in docker blocked accessing other docker containers

[Whitestrake (Matthew Fay)]

Because in the second version, you’re not pinning it into a subfolder.

You’re effectively solving the issue with option 2.A. from my post.

Option 2: In Caddy

A. By giving up the web root

You can use a subdomain instead, e.g. sonarr.example.com, and proxy the entire web root. This configuration precludes the issue described above and will work for absolutely any HTTP application.
