What is WebSocket?

WebSocket allows you to send and receive messages is a computer communications protocol that enables messages to be sent to and from the server. Basically, it is a way means of communication between you and the server. The WebSocket specification defines an API for 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 sides of the connection can start sending data at any time. The XTM Workbench application uses WebSockets to establish the connection.

The WebSockets are quite sensitive for to some online software that may impact has the potential to affect the connection. Sometimes, the direct cause of the WebSockets disconnections is the software installed on the user - end, such as:

• browser plugins/extensions;,

• firewalls;,

• VPNs (Virtual Private Network);,

• CDNs (Content Delivery Network).

When If the disconnects are happeningoccur, it is always a good idea to temporarily disable the software and see if it helpedthat helps. If that does not yield desirable results, please, click here the required results, see XTM Workbench – most common issues & troubleshooting and follow the basic steps from described in the article.
