What is WebSocket?

WebSocket allows you to send and receive messages to and from the server. Basically, it is a way of communication between you and the server. The WebSocket specification defines an API establishing "socket" connections between a web browser and the machine. In other words, there is a persistent connection between you and the server, and both parties can start sending data at any time.

Specifics

In order to be sure, though, the proper investigation is required. As a user, you can help out the XTM support team by providing the relevant information from your side to facilitate the issue resolution,

NO_BROWSER_PING

The NO_BROWSER_PING issue occurs when the XTM application cannot ping the browser anymore, which leads to the WebSockets disconnection. This is rather a user-end issue, and the connection between the browser and XTM Workbench can be blocked by, for example, some software.

WebSockets can be tested with online tests: WebSocket tester.

Good to know!

In most cases, WebSockets issues occurring on the user-end and the XTM support team is often unable to directly solve such issues. However, sometimes the problems only seem to lie on the users' end, but it eventually turns out that this is an XTM issue and we need to make some changes. Irrespective of root cause, please, do not hesitate to reach out to the XTM support team with all the above-mentioned information gathered up.
