1. Caddy version (caddy version):
2.3.0
2. How I run Caddy:
I have a couple of raspberry pis, one running nextcloud in a snap and one running a Joplin server in a docker container. CAddy is running on the one also running the joplin server. For the moment, I am just trying to get the reverse proxy to Nextcloud working, and I can’t.
a. System environment:
This is 64bit Raspberry OS; caddy is running plain, ie not in any sort of container
Nextcloud is in a snap installation, with apache, which works when contacted directly
b. Command:
caddy run / reload
c. Service/unit/compose file:
paste full file contents here
d. My complete Caddyfile or JSON config:
My caddyfile is
localhost {
respond "Hello, World. I don't believe this but it works"
log
}
unclaimed.space {
route {
reverse_proxy /nextcloud/* https://192.168.178.46:443 {
header_down Strict-Transport-Security "max-age=15552000;"
header_down X-Real-IP {http.request.remote}
header_down X-Forwarded-For {http.request.remote}
}
reverse_proxy /joplin/* localhost:22300
respond "Yes, I do have a certificate, thank you: now go away."
}
log
}
joplin.unclaimed.space {
reverse_proxy localhost:22300
log
}
nextcloud.unclaimed.space {
reverse_proxy http://192.168.178.46:81 {
header_down Strict-Transport-Security "max-age=15552000;"
header_down X-Real-IP {http.request.remote}
header_down X-Forwarded-For {http.request.remote}
}
log {
output file /var/log/caddy.log
format console
}
}
# DO NOT FORGET
#
# to run "caddy reload" after every change
The two unproxied responses work.
The proxy to nextcloud does not.
Neither does the one to joplin, but that has to be a variant of the same problem
3. The problem I’m having:
When I enter https://nextcloud.unclaimed.space into my browser, I get
This page isn’t workingnextcloud.unclaimed.space redirected you too many times.

4. Error messages and/or full log output:

5. What I already tried:
Endless googling for possible answers; adding the header lines you see into the configuration; running nextcloud on different ports; trying with http and without.
I’m sure I’m missing something obvious and stupid but I don’t know what.
