Pandora port on Synolgy LMS

I have LMS running on a synology box. I recently installed an Adtrap (ad blocker). The issue is that now I can not play pandora stations. I can see my stations, but can't play any of them. I get a message from the squeezebox that it has been blocked. I don't know what ports to open on the squeezebox to enable it to work. Do you have any ideas?

I also can't play my plex from outside the home, but that's a post for another location.

Thank you
