WebSocket drops every 45s in Cognigy AppFoundry integration

The connection dies exactly at the 45s mark. No error payload comes through, just a silent disconnect on the client side.

The server-side handler looks standard:

const ws = new WebSocket(process.env.WS_URL);

ws.on(‘open’, () => {
console.log(‘Connected’);
});

Is this a known timeout in the NICE CXone gateway or do I need to send a ping manually?
