I’m trying to install Nextcloud on my server with Docker using a Caddy reverse proxy. Caddy is working for other services so I will just copy the Caddyfile here.
My issue is that on the host machine with localhost it is working, with the IP it says it is not a trusted domain, and with my domain it says “502 Bad Gateway”. Please help I’ve already tried multiple configurations but can not get it working.
Caddyfile:
{domain} {
tls {email}
tls {
dns godaddy
}
# Enable basic compression
gzip
# Service discovery via well-known
redir /.well-known/carddav /remote.php/carddav 301
redir /.well-known/caldav /remote.php/caldav 301
proxy / http://nextcloud:8080 {
# X-Forwarded-For, etc...
