Winsock error 10048 is an error you may encounter when using the Internet. It occurs when a program or process tries to access the network but cannot connect with the server.

Similarly, we also have another Winsock error 10054, so be sure to check out our guide on the same. 

What does Winsock error mean?

A Winsock error is a specific kind of network error. It can happen in any operating system but is most commonly associated with Windows. 

Winsock refers to the Windows Sockets API, a set of functions built into Windows that allow applications to communicate over TCP/IP networks. These functions are used by programs to handle network connections and send data between computers on the Internet.

A Winsock error occurs when an application attempts to connect to another computer using the TCP/IP protocol but can’t establish a connection. This can happen for a variety of reasons, including:

• Outdated drivers – Outdated drivers can also cause win socket errors on your computer as they might not be compatible with the latest operating systems or security updates released by Microsoft.
• Incorrectly configured proxy settings – If you’re using a proxy server and have recently updated your computer’s network settings, it’s possible that you’ve accidentally disabled them. 
• Firewall settings – A firewall or antivirus application may be blocking the connection between your computer and the server you are trying to connect with.
• Faulty hardware – Another possible cause of this error could be faulty hardware, such as a bad network card or bad cables. 
• Virus infection – You may have a virus or malware on your computer preventing you from connecting to the internet.

How do I fix Winsock error 10048?

When you get a Winsock error message, it can be difficult to diagnose the problem. The message you see depends on the type of error your computer is experiencing.

The following are some common basic troubleshooting steps you can try your luck with:

• Check that all of your network connections are enabled and working properly. 
• Perform a network speed test to ensure your connection is stable.
• Run Windows Update.

Firewalls are used to block unauthorized access to your computer from the Internet. If you have a firewall enabled, it may be blocking access to the Internet or preventing your computer from connecting properly to websites and servers on the Internet.

If so, then configure your firewall settings properly so as not to block access to services.

2. Update the network driver

1. Hit the Windows key, type Device Manager in the search bar, and click Open.

Socket Error 10048 — Specified Address Already in Use

Method 1

Method 2

Overview

This article will guide you through resolving Error Code 10048 – “Only one usage of each socket address (protocol/network address/port) is normally permitted. [WSAEADDRINUSE (0x2740)]”. This error occurs when multiple processes attempt to use the same port, leading to system performance issues.

Identifying the Problem

Causes: Error Code 10048 is typically caused by:

• Conflicting applications using the same port
• Binding a port that is already in use
• Misconfigured network settings

Symptoms:

• Applications failing to start or connect
• Network connectivity issues
• System performance degradation

Common Fixes

1. Restart the System:

• Restarting your system can free up the port and resolve the error.

2. Check for Conflicting Applications:

• Determine which applications are using the conflicting port.
• Close or disable the applications that are not essential.

3. Use a Port Scanner:

• Use tools like TCPView or PortQry to identify the process using the conflicting port.
• End the process to free up the port.

4. Adjust Network Settings:

• Check your router or firewall settings to ensure that the required ports are open.
• Reassign the conflicting port to a different one in the network settings.

Advanced Troubleshooting

1. Modify the Windows Registry:

• Open the Registry Editor (regedit.exe).
• Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters.
• Create a new DWORD value named “TcpTimedWaitDelay” and set its data to a higher value (e.g., 30000).

2. Reset the TCP/IP Stack:

• Open an elevated command prompt.
• Run the following commands:

netsh int ip reset
ipconfig /flushdns

• Restart your system.

Conclusion

Error Code 10048 can be resolved effectively by following the solutions outlined above. Restarting the system, identifying and closing conflicting applications, adjusting network settings, modifying the registry, or resetting the TCP/IP stack can help resolve the issue. To prevent future occurrences, it is advisable to use port management tools to monitor port usage and avoid conflicts.
