1. The problem I’m having:
I started Caddy with a docker compose and I would like to use it as reverse proxy to serve a Plane self-hosted instance started with another docker compose. Without any success…
Somebody has a guide to configure Caddy and Plane in this configuration?
In advance, thank you!
2. Error messages and/or full log output:
A obtain always the ERR_TOO_MANY_REDIRECTS error.
3. Caddy version:
2.9.1
4. How I installed and ran Caddy:
a. System environment:
OS: Raspbian server
b. Command:
I follow the user guide of Plane to install and start the Plane self-hosted
So, start first the docker compose of Plane through the Plane setup script

Then start the docker compose of Caddy.
