Transmission-OpenVPN UI Access

So I installed this rockon and everything went fine, except I cannot access it through the web UI. So I tried following the documentation related to this issue and tried to reverse proxy the traffic through another container and I get he error “unable to find image”. See screenshot as I input the referenced image for that docker? So not sure whats going on and how to fix this.

Thanks,
William

Sorry jumped the gun had the wrong ID. With the correct ID I get this error

Thanks
