Troubleshooting In-App Notification Issues with Websockets

I got this question from one of our community members: "I am trying to integrate In-App notifications in my applications. I have deployed novu in seperate VM. Triggering working fine. But unable to get notification using socket in browser console I am getting Error: websocket error."

I'm having a similar issue, "Invalid frame header" this is a new issue, things were previously working and there are no changes that I am aware of on the novu configuration
