Xcaddy build not working

phospho · July 13, 2025, 3:52pm

1. The problem I’m having:

Hi guys !

So I’m tying to setup caddy as a reverse proxy to use Jellyfin on the go. But I can’t get the cloudflare DNS module installed, it seems to me the xcaddy build is not working properly despite the build log not showing any errors (see under build log then "caddy list-modules output)

2. Error messages and/or full log output:

a. System environment:

I'm running proxmox 8.4.0, caddy is installed in an unprivileged LXC

b. Command:

xcaddy build --with github.com/caddy-dns/cloudflare

c. My complete Caddy config:

cannot get it to install properly

The binary generated by xcaddy is in the current directory, which can be invoked by running ./caddy. You’re running the Caddy binary that’s in your PATH.
