Waht TCP ports does vatsim use

i am trying to get xpilot to work

vpiloted worked when i was using it for fsx and fs2020

but when i switched over to xplane and tried the xpilot, it connected but my location is not showing up and i cannot talk on the radio.

my firewall has all udp ports open. i am wondering if it is a TCP port, but i tried 6809 and some other ones which didn’t work.

i am also suspicious that the firewall or network is blocking a specific IP address that it needs to connect to.
