A WebSocket communications protocol is used in Cortex XSOAR for bi-directional data transfer between the client browser and the server. WebSocket communication enables data to auto update without refreshing the browser.
If a user experiences a slow response from the Cortex XSOAR server and does not receive data updates on certain pages and actions, the WebSocket may be disconnecting. The causes of WebSocket disconnects are:
The network proxy killing the WebSocket connection.
Slow connection between server and client.
If the network proxy is the cause, adjust network proxy settings to allow WebSocket connections.
Check the throughput between server and client.
Verify the System Diagnostics page does not show alerts for large incidents, context, tasks, etc.
