A fatal error occurred while creating a tls client credential. the internal error state is 10013.

In the realm of cybersecurity, encountering errors is not uncommon. One such error that often perplexes users is TLS Error 10013. Transport Layer Security (TLS) is crucial for securing communication over computer networks. When an error like 10013 occurs, it can disrupt operations and lead to frustration. However, understanding the nature of this error and how to troubleshoot it is key to overcoming it effectively.

Understanding TLS Error 10013

TLS Error 10013 typically indicates an issue with socket permissions on a Windows system. It signifies that an application is attempting to access a socket in a way that is forbidden by the operating system or other software restrictions. This error can manifest in various scenarios, such as when configuring TLS settings for network communication or when running server applications.

Common Causes of TLS Error 10013

Several factors can contribute to the occurrence of TLS Error 10013. Here are some common causes:

  1. Insufficient Permissions: The application may not have the necessary permissions to access the socket or perform the required operations.
  2. Firewall Restrictions: Firewall settings or other security software may be blocking the application’s access to the socket or network resources.
  3. Port Conflicts: Another application or service may be using the same port, causing a conflict that results in the error.
  4. Corrupted Installation: In some cases, a corrupted installation of the application or the underlying TLS library can trigger Error 10013.

Troubleshooting Steps

Resolving TLS Error 10013 requires a systematic approach to identify and address the underlying issue. Here’s a comprehensive troubleshooting guide:

1. Check Application Permissions

Ensure that the application has the necessary permissions to access network resources and create sockets. This may involve adjusting user permissions or running the application with elevated privileges.

2. Review Firewall Settings

Inspect the firewall settings on the affected system to determine if they are blocking the application’s access to the network. Whitelisting the application or configuring firewall rules to allow the required traffic can help resolve the issue.

3. Identify Port Conflicts

Use network diagnostic tools to identify any port conflicts on the system. If another application is using the same port required by the affected application, consider reconfiguring the port assignments or stopping conflicting services.

4. Update or Reinstall the Application

If the error persists, consider updating or reinstalling the application experiencing the issue. A corrupted installation or outdated version of the application may be contributing to the problem.

5. Verify TLS Configuration

Double-check the TLS configuration settings used by the application. Ensure that the correct protocols, cipher suites, and certificate authorities are configured to establish secure connections.

6. Monitor System Logs

Review system logs and error messages for any additional information that may shed light on the root cause of the problem. Look for specific error codes or messages that can guide further troubleshooting efforts.


TLS Error 10013 can be a challenging issue to resolve, but with a systematic approach and the right troubleshooting techniques, it can be overcome. By understanding the underlying causes of the error and following the steps outlined in this guide, you can effectively diagnose and resolve TLS Error 10013, ensuring smooth and secure network communication.

Remember, patience and persistence are key when troubleshooting complex network issues. Don’t hesitate to seek assistance from online forums, documentation resources, or experienced professionals if you encounter difficulties along the way. With determination and diligence, you can conquer TLS Error 10013 and maintain a secure computing environment.
