P2 Connection to console issues

I'm trying to connect a P2 to a password enabled WiFi network in an environment where I don't have easy access to the IT team so would like to make sure I have as much troubleshooting and direction as possible when I make that connection. Here are the particulars:

  • confirmed that with proper SSID PW, I can browse right to the web with no further authentication on my phone
  • I see the "6" above the WiFi symbol on my phone WiFi list for this SSID
  • the P2 connects to the WiFi but can't connect to the particle cloud
  • If I setup my phone as a hotspot and have the P2 connect to it, while my phone is on the target WiFi network, the P2 cannot connect to the cloud. As soon as I turn off WiFi on my phone and the phone connects to the 5G data, the P2 does connect to the cloud.

Below is the log I get when it is connecting directly to the target WiFi and fails to connect to the cloud:

0000170625 [comm.dtls] ERROR:

So I'm looking for general support but a couple of specific questions come to mind:

What port does the P2 need open to connect to the cloud?
Does the P2 function in an IPv6 environment?
What is the list of parameters/settings that need to be present on a WiFi configuration for success with a P2?

Thanks!
Matt

It looks like the network firewall is either preventing outgoing UDP, or blocking incoming UDP from being forwarded to the P2.

0000077617 [comm.dtls] ERROR: handshake failed -6800
0000077626 [comm.dtls] ERROR: Invalid handshake state
0000077635 [comm.protocol.handshake] ERROR: Handshake failed: 17

This line lists a valid Particle cloud server IP address, so DNS is not getting blocked or redirected (captive portal) so that's good.

0000125915 [system] INFO: Cloud socket=0, connecting to 3.230.254.13#5684

There's more information here, but UDP port 5684 outbound. The firewall will typically create a dynamic port for the response packets and forward the response back to the P2, but this could be blocked.
