Hi, I'm having trouble getting my Caddy reverse proxy to work with the arr apps I can access everything without the reverse proxy. I have set the basic login prompt (like this one) through the arr apps after I logge in to one of the arr apps I either get a blank page or I'm seeing this error page:
firefox
The page isn’t redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
This problem can sometimes be caused by disabling or refusing to accept cookies.
chromium
This page isn’t working
domain.com redirected you too many times.
Try deleting your cookies. ERR_TOO_MANY_REDIRECTS

}

header_up Host {host}
header_up X-Real-IP {remote_host}
header_up X-Forwarded-For {remote_host}
header_up X-Forwarded-Proto {scheme}
}
}
}
I've tried setting the URL base to /the_name_of_the_arr_app, but it didn't work. I've attempted it with and without the redir /the_name_of_the_arr_app /the_name_of_the_arr_app/. I'm stuck and unsure of how to resolve the issue. It works fine with qBittorrent.
