I’m trying to connect a browser html5 client to a dedicated server. Connecting to the server works as a standalone client but not from a browser.  
I’m using Firefox 62.0.2 to run the game.  
The web console returns [this](https://pastebin.com/raw/ajht2wAf) when trying to connect.

Edit: It seems like the /Script/HTML5Networking.WebSocketNetDriver isn’t working. The dedicated server prints this when trying to use the WebSocketNetDriver as the only net driver:

```
CreateNamedNetDriver GameNetDriver already exists as WebSocketNetDriver_0
NetworkFailure: NetDriverCreateFailure, Error: ''

```

Is the HTML5Networking Net Driver supported at all? Or is only not working on MacServer platform?
