Websocket disconnects during concurrent session load test

NICE CXone API & Integrations
1

Background

Running JMeter 5.6.2 to simulate 500 concurrent agents connecting to Genesys Cloud. Targeting the websocket endpoint for real-time data.

Issue

Connections drop randomly after 100 concurrent users. No 429s. Just silent disconnects.

Troubleshooting

  • Checked network logs. No firewall drops.
  • Reduced concurrency to 50. Stable.
  • Using standard OAuth2 flow.

Any limits on websocket connections per tenant? Or is this a client-side timeout issue?
