Live Link Face will not connect to UE 5.6

I can’t get an iPhone 13 Pro to connect using Live Link Face/Live Link Hub. When I click on connect, it says “connecting” but never connects. ARKit works fine, so I don’t think it’s an IP/WiFi/Router issue. ANY info would be greatly appreciated. Here’s what I have tried so far:

Made sure they are on the same network
Local Network is enabled on iPhone
IP address and ports match
Made sure that Unreal and Port# is not blocked by Windows Defender
Tried multiple port numbers
Restarted Unreal, computer, router, and phone
Cleared cache and temp files for Unreal and Windows
Deleted and reinstalled Live Link Face app
Tried Unicast and Static Endpoints in project settings
