Streaming Remotely LMS files won't play but streaming services work

I know this has probably been covered before, but I have found that I cannot stream music from MyMusic to a remote player (squeezelite) if I am on my works network, I can connect to the players just fine, I can play radio stations and streaming services fine, but MyMusic doesn't work. I have verified that it is my works network because everything works fine when I connect via my phones Internet connection though WiFi. It appears to start playing but there is no sound when this happens.

I am not using VPN or SSH yet, so I am wondering is this is a port issue (do I need port 9090) or will SSH work, or what else.
