WebSocket is a technology that enables two-way realtime communication between client and server. In contrast, Socket.IO is a library that provides an abstraction layer on top of WebSockets, making it easier to create realtime applications.

Why is WebSocket not connecting to server?

The “WebSocket unable to connect” error message indicates that you are likely working behind a proxy that doesn't support the WebSocket protocol. In this case, the device connections will switch to the HTTP protocol.

What causes a WebSocket to fail?

The most common cause of Websocket error is when you connect to DSS through a proxy. Websockets is a fairly recent protocol and many enterprise proxies do not support it. The websocket connection will not establish and you will see this message.

Is WebSocket on TCP?

The WebSocket protocol is an independent TCP-based protocol. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request. By default the WebSocket protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket connections tunneled over TLS [RFC2818].

Is WebSocket always open?

1 WebSockets are open as long as you want and are not hackish (like long-polling and other alternatives).
