1. Caddy version (caddy version):
v2.4.6 h1:HGkGICFGvyrodcqOOclHKfvJC0qTU7vny/7FhYp9hNw=
2. How I run Caddy:
as a service. see Install — Caddy Documentation
a. System environment:
- Debian 11 (bullseye)
- lighttpd/1.4.59 with dav
d. My complete Caddyfile or JSON config:
dav.myserver.de {
reverse_proxy localhost:11337
}
(That’s really the complete config. In the whole report, I ran a replace on the domain name and changed it to “myserver”)
3. The problem I’m having:
- moving/copying files on a webdav server behind caddy fails. (status: 400)
- moving/copying them without caddy (localhost:11337) works.
- all other webdav operations are working as intended. (as far as I can tell. See #5 What I already tried)
4. Error messages and/or full log output:
I tried to move rename /foo2 to /foo using cadaver, which resulted in this log:

I compared the lighttpd log, but there is nothing except for the URI and timestamps. And of couse the status code
