How to connect radarr in unRAID to windows nzbget

Ok so I've got my normal radarr, sonarr and nzbget running on a windows 10 machine. My 4K radarr, anime (TV) and 4k sonarr run on unRAID.

I can't seem to connect the ones running in unRAID out to the windows machine, but vice versa I can.

Nzbget comes up as 127.0.0.1:6789 on windows. Even if I try to connect to windows with it's IP I still get nowhere.

The reason I have it setup this way is because my unRAID is doing to much CPU work with everything I have running, and it's messing with Plex so I'm offloading certain things until I can upgrade.
