ok I give up for today. Being fighting to get my port5432 open and although it's configured in my router, I can't see it from outside as open

Weird thing is: I have a Postgresql db installed in my raspberry. I can connect to it using tailscale VPN that comes with my umbrel so somehow that port works in the raspberry..

But if I check from outside the vpn, just checking the port... it looks closed and I don't know why
