Research direction

Start with Assets/WebSockets/WebSocket.cs at line 471 and reproduce the connection using wss://api.devnet.solana.com/ in the editor or a mobile build, comparing it with wss://devnet.genesysgo.net/. Use the provided stack trace and platform differences to determine the failure; done means the affected URL connects successfully outside WebGL without relying on BestHTTP.

Description

Hey,
when i try to connect to this url, it works fine in the WebGL builds but not in editor or mobile builds:
wss://api.devnet.solana.com/

The error is:
Error! Unable to connect to the remote server

This URL works in Editor:
wss://devnet.genesysgo.net/

Any Ideas how I can solve the problem? Or in which direction I need to look?
When I use BestHTTP package it works, so I assume there should be some way this can be fixed in this package hopefully.

This is the Stacktrace:
