Introduction

WebSocket is a protocol that provides a full-duplex communication channel over a single TCP connection between a client and a server. It allows real-time data transfer between two endpoints. System.Net.WebSockets is a namespace that provides the infrastructure for developing WebSocket-enabled applications on the .NET platform. However, sometimes, you may encounter an error that says System Net WebSockets WebSocketException 0x80004005. In this article, we will discuss this error and provide solutions to fix it.

What is System Net WebSockets WebSocketException 0x80004005 Error?

The error message System Net WebSockets WebSocketException 0x80004005 is related to WebSocket communication. This error occurs when the WebSocket connection between the client and server fails to establish or maintain. The error code 0x80004005 indicates an unspecified error. There can be multiple reasons behind this error. It can be due to network connectivity issues, server-side problems, client-side issues, or misconfiguration of the WebSocket application.

Reasons Behind System Net WebSockets WebSocketException 0x80004005 Error

Network Connectivity Issues: The WebSocket connection requires a continuous network connection between the client and server. If the network connectivity is unstable or interrupted, the WebSocket connection can fail, resulting in the System Net WebSockets WebSocketException 0x80004005 error.
Server-Side Problems: The server-side application that implements the WebSocket protocol can have issues that can cause the error. For example, if the server application crashes or becomes unresponsive, the WebSocket connection can fail.
Client-Side Issues: The client-side application that initiates the WebSocket connection can also cause the error. For example, if the client application sends incorrect WebSocket frames or disconnects abruptly, the WebSocket connection can fail.
Misconfiguration of the WebSocket Application: If the WebSocket application is not configured correctly, it can cause the System Net WebSockets WebSocketException 0x80004005 error. For example, if the WebSocket endpoint URL is incorrect or misconfigured, the WebSocket connection can fail.

How to Fix System Net WebSockets WebSocketException 0x80004005 Error?

Check Network Connectivity

The first step in fixing the System Net WebSockets WebSocketException 0x80004005 error is to check the network connectivity between the client and server. You can use the ping command to check the network connectivity. Open the command prompt and type the following command:

ping [IP Address or Domain Name]

If the ping command returns a response, the network connectivity is fine. If the ping command fails, there can be an issue with the network connectivity. You can try the following steps:

Check the network cables and connectors.
Restart the modem and router.
Contact your network administrator.

Check Server-Side Application

If the network connectivity is fine, the next step is to check the server-side application that implements the WebSocket protocol. You can check the server logs or console output for any errors or exceptions. If there are any issues with the server-side application, you can try the following steps:

Restart the server-side application.
Update the server-side application to the latest version.
Contact the server-side application developer.

Check Client-Side Application

If the server-side application is fine, the next step is to check the client-side application that initiates the WebSocket connection. You can check the client-side logs or console output for any errors or exceptions. If there are any issues with the client-side application, you can try the following steps:

Update the client-side application to the latest version.
Check the client-side code for any errors or issues.
Contact the client-side application developer.

Check WebSocket Application Configuration

If both the server-side and client-side applications are fine, the next step is to check the WebSocket application configuration. You can check the WebSocket endpoint URL and other configuration settings. If there are any issues with the WebSocket application configuration, you can try the following steps:

Update the WebSocket application configuration to the correct settings.
Check the WebSocket endpoint URL for any typos or errors.
Contact the WebSocket application developer.
