Google Nest Wifi issues

[MoreTrife]

Recently moved and had to buy new router. Chose Google Nest Wifi router. Having trouble opening up ports through Home app. Any tips of suggestions? I used Settings, opened up Port 4040 on computer Subsonic is on, got as far as successfully registering myname.subsonic.org but couldn't get it from outside. Thought maybe it was static IP issue. Tried assigning IP via Home app but not having success. Please help!
