Reverb Issue - WebSocket Connection Failed

I'm having an issue with Laravel Reverb.

Ive set up everything, enabled reverb via laravel forge, but for some reason Im not receiving a console error:

WebSocket connection to 'wss://data-cloud.test:8080/app/a5sokxlpubir0yddvrv6?protocol=7&client=js&version=8.4.0&flash=false' failed:  pusher.js:3742 

Its also trying to connect to my 'Valet Test Domain' on my live server???

The daemon is running on forge and my env is populated with the correct variables.

I've also added a cname record on Digital Ocean, and can access ws.myDomainName in the browser.

Anyone any ideas what might be going on?
