Genesys Cloud Guest API WebSocket connection dropping after 60s

Hey folks,

We’re building a custom chat UI using the WebSocket-based Guest API instead of the default widget. Everything works fine for the first minute, but then the connection drops with a close code of 1006. No error payload in the response, just silence. We’re using the standard wss://api.mypurecloud.com/webmessaging/v1/sessions endpoint. Has anyone hit this timeout issue? Is there a keep-alive mechanism we’re missing?
