1. The problem I’m having:
I want to serve a simple HTML page in response to an http request. I used the example provided in the docs
2. Error messages and/or full log output:

3. Caddy version:
2.6.2
4. How I installed and ran Caddy:
apt-get install -y --no-install-recommends caddy
a. System environment:
It’s a docker image based on Cloudron’s app base image. I believe it’s Ubuntu based.
b. Command:
/usr/local/bin/gosu cloudron:cloudron /app/code/bin/agate --content /app/data/public/ --certs /app/data/certs/ --addr 0.0.0.0:1965 --hostname ${CLOUDRON_APP_DOMAIN} --lang en-US
c. Service/unit/compose file:
Not sure what that is in my case.
d. My complete Caddy config:
http:// {
