[HELP} Join server error: "Failed to Establish P2P Connection with server"

[Twinkle Toes]

Hello,

I am attempting to connect to PZ steam server, 32 bit, where I am the host and the client. I can see the ping and status of the server in the game's server explorer. I get the "Failed to Establish P2P Connection with server" error in game after clicking "Join Server". My friend tried setting up a server in the same way an gets the same error. Any help would be appreciated, I love this game!

Below is the server responses and client side responses.

It looks like lines: "P2P connection failed: 4
Failed,P2PSessionConnectFail"
Could be the culprit? I hid my IP address.

Ports have been forwarded, firewall excpetion made. I have tried both public and LAN IP address.

Instead of launching the PZ Dedicated Server from within Steam, go to where the files are located locally and launch either the 'StartServer32' or 'StartServer64' bat files. This solved the issue for me anyways!
