WebSocket connection to 'wss://zello.io/ws/' failed

[codymatthew]

I am getting the following errors when loading the code below. I have not maxed out the connections, I waited over 24 hours before running the code again and I'm getting the same error. The error is reproduced both locally and from a https website.

Edge: WebSocket connection to 'wss://zello.io/ws/' failed: Error during WebSocket handshake: Unexpected response code: 429
