Research direction

Start with Assets/Scripts/Clients/CortexClient.cs:56 and reproduce the TLS handshake using the LAN address instead of localhost in the Unity editor. Compare the failing Unity connection with the working wscat connection and inspect the NativeWebSocket package at WebSocket/WebSocket.cs:478. Done means the Unity editor and a compiled VR device can connect to the stated local websocket server over its LAN address.

Description

PROBLEM

Im trying to connect to a websocket server hosted on my lan at wss://192.168.0.42:6868. It doesn't require authorization.

The websocket client fails the TLS handshake if i use an external ip like wss://192.168.0.xxx:6868 but it works fine if i use wss://localhost:6868

DETAILS

I can connect via the the TUI app wscat, but when I try to connect via the Unity editor I get the following error:

Connection Error! Please double check your URL and ensure the cortex API is runningURL: wss://192.168.0.42:6868 Error: Unable to connect to the remote server
UnityEngine.Debug:LogError (object)
CortexClient:<Start>b__13_1 (string) (at Assets/Scripts/Clients/CortexClient.cs:56)
NativeWebSocket.WebSocket/<Connect>d__27:MoveNext () (at Library/PackageCache/com.endel.nativewebsocket@c5101c0776/WebSocket/WebSocket.cs:478)
UnityEngine.UnitySynchronizationContext:ExecuteTasks () (at /Users/bokken/buildslave/unity/build/Runtime/Export/Scripting/UnitySynchronizationContext.cs:107)

Ideally I'd like to connect to the same local web socketserver over the local network on the Unity editor, and via a compiled device in VR.
