Introduction
WebSocket is a communication protocol that allows two-way communication between a client and a server over a single, long-lived connection. It is used in web applications that require real-time communication, such as online gaming, chat applications, and stock trading platforms.
WebSocket has become increasingly popular due to its many advantages over traditional HTTP requests. It is faster, more efficient, and provides real-time updates without the need for constant polling.
However, like any technology, WebSocket is not without its issues. One common problem that developers face is the WebSocket Close 1005 error. In this article, we will explore what this error is, what causes it, and how to fix it.
What is WebSocket Close 1005?
WebSocket Close 1005 is an error code that is returned when a WebSocket connection is closed without an error. In other words, it indicates a clean, graceful closure of the connection.
The WebSocket protocol defines several error codes that can be returned when a connection is closed, ranging from 1000 to 1015. Each error code has a specific meaning, such as indicating that the connection was closed due to an internal server error, a protocol error, or a policy violation.
However, when a WebSocket connection is closed without an error, the server returns the 1005 error code. This is because the WebSocket protocol does not define a specific code for a clean, graceful closure.
What Causes WebSocket Close 1005?
There are several possible causes of the WebSocket Close 1005 error. Some of the most common include:
- Client Disconnect: The client may have disconnected from the server, either intentionally or unintentionally. This can occur if the client closes the connection or if there is a network interruption.
- Server Shutdown: The server may have been shut down or restarted, causing the WebSocket connection to close.
- Idle Timeout: Some WebSocket servers are configured to automatically close connections that have been idle for a certain period of time. This can result in the WebSocket Close 1005 error if the connection is closed without an error.
- Firewall or Proxy: Some firewalls or proxies may terminate WebSocket connections that have been open for too long or that have exceeded a certain amount of data transfer. This can also result in the WebSocket Close 1005 error.
How to Fix WebSocket Close 1005
Fixing the WebSocket Close 1005 error depends on the cause of the problem. Here are some possible solutions:
Client Disconnect
If the client has disconnected from the server, you can try to reconnect to the WebSocket server. Make sure that your code handles connection errors gracefully and retries the connection as needed.
Server Shutdown
If the server has been shut down or restarted, you will need to wait for it to come back online before reconnecting to the WebSocket server.
Idle Timeout
If the WebSocket connection is being closed due to an idle timeout, you can try to keep the connection alive by sending periodic messages to the server. This can prevent the connection from being closed due to inactivity.
Firewall or Proxy
If the WebSocket connection is being terminated by a firewall or proxy, you may need to configure the firewall or proxy to allow WebSocket traffic. You can also try to reduce the amount of data that is transferred over the WebSocket connection to avoid triggering the firewall or proxy.
FAQ

What are some possible causes of WebSocket Close 1005?
Some possible causes of WebSocket Close 1005 include client disconnect, server shutdown, idle timeout, and firewall or proxy termination.
How can I fix WebSocket Close 1005?
To fix WebSocket Close 1005, you will need to identify the cause of the problem and take appropriate action. This may involve reconnecting to the WebSocket server, keeping the connection alive with periodic messages, or configuring firewalls or proxies to allow WebSocket traffic.
Is WebSocket secure?
WebSocket can be secured using SSL/TLS encryption. This provides end-to-end encryption of the data being transmitted over the WebSocket connection, protecting it from interception or tampering.
