Unable to start Caddy container

[ker0x]

Hello

I'm facing this error when running docker-compose up.

It occurs on both Ubuntu and Windows (through WSL2)

I'm facing the same problem on MacOS.
EDIT: I both up- and downgraded caddy to 2.2.1 and 2.4-beta, but the issue seems to remain the same.
EDIT2: After disabling vulcain in Dockerfile and Caddyfile the caddy container stays alive.

Same here. Fresh ubuntu 20.04/docker installation

It's probably related to caddyserver/caddy#3525. I'm taking a look.

This PR should fix the problem: #125
Can you try if it works for you? Thanks!

@dunglas it works fine with the fix, thanks you!
