Proxying transmission web interfaces results in connection failed error

anon74401780 · February 14, 2019, 4:08pm

Hey Guys,

im trying to proxy transmission. I keep getting a connection failed error.
transmission-error

Visiting 10.0.0.2/bullshit/web/ directly works as intended. While searching for a solution i only found nginx configs, which simply use proxypass and proxypassrevers. The error leaves no trace in the transmission log.

Im hosting transmission on ubuntu xenial using transmission-daemon version 2.84 (14307)

My current config looks like this. Everything i uncommented didn’t change the outcome:

        basicauth "XXXX" XXXXX {
        /test/transmission

        }

        proxy /test/transmission 10.0.0.2/bullshit/web/ {
        transparent
		without /test/transmission
#       websocket
#       keepalive 0
#       header_upstream X-Transmission-Session-Id hpUJUDunPasgl7kU3JUmO6YOsrp61v9HHZh23JDxeEDHtWSK
#       header_upstream X-Transmission-Session-Id "<X-Transmission-Session-Id"
        }

Hi @anon74401780, welcome to the Caddy community.

This one looks pretty complex. My advice is to simplify as much as possible (including removing subfolders and proxying an entire subdomain instead, at least while testing).

The error logs you gave show requests for /test/rpc, but I don’t see any config in your post that tells Caddy how to handle requests for /test/rpc.

Hi @Whitestrake thank you very much for your advice!
It works with a subdomain and thats fine for me.
