Websocket error

[kwiens]

I tried following the Quickstart instructions but hit this error:

WebSocket error: Error: socket hang up
    at connResetException (node:internal/errors:717:14)
    at TLSSocket.socketOnEnd (node:_http_client:526:23)
    at TLSSocket.emit (node:events:525:35)
    at TLSSocket.emit (node:domain:489:12)

    at processTicksAndRejections (node:internal/process/task_queues:82:21) {
  code: 'ECONNRESET'
}
Disconnected from proxy: <Buffer >

Can you provide any additional debugging suggestions? I supplied a .env file but made no modifications to the demo code.
