What is A Fatal Error Occurred While Creating a TLS Client Credential?

A fatal error occurred while creating a TLS client credential an error and it appears when the message sent by the server to your device is not being understood by your device during the connection setup. Now, let’s begin with the TLC. TLC is Transport Layer Security, and it gives a security layer between the Client and server. For example, if you visit any of the websites from your device, the server sends the security certificate to your device about how genuine the server is. This activity is performed by the TLS with the help of its trained and generated security protocol.

A fatal error occurred while creating a TLS client credential error called The internal error 10013. This error mostly happens on the Windows 10 and 11 operating systems. The reason for the error can be your old software program, or the TLS version is outdated, and many more. The latest versions of TLS are TLS 1.2 and TLS 1.3.

To help you out better, I have shared below all the easy fixes that you can try from your end to get idea about system errors.

1. Enable TLS 1.0/1.1 Using Internet Properties

The first attempt you can make to solve your TLS error 10013 is to switch your TLS 1.0 to TLS 1.1. However, this is not a permanent solution, but it can help you to solve your error. I have shared below easy steps if you have not done it before.

1. First of all, go to the taskbar search box and enter the keyword Internet options.
2. Now, you will see the Internet panel on the screen.

4. Now, choose TLS 1.0 and TLS 1.1 by clicking on the checkboxes.
5. At the end, click on the Apply button to update all the changes.

2. Change Values in the Registry

The second solution on the list is to change the values in the registry TLS programs. I have shared some easy steps that you can follow for that.

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
5. Now, visit the right panel, choose the protocol option, and right-click on it.
6. Visit the New and then click on the Key and name it TLS 1.2. ( protocols >> New >> Key >> name TLS 1.2)
7. Just like above, right-click on “TLS 1.2” and visit “New,” and then Click on “Key” and name it “Client”. (TLS 1.2 >> New >> Key >> name Client).
8. Now, you need to right-click on the Client button and visit “New” and then Click on “DWORD (32-bit) Value.” and give a name to it.
9. “DisabledByDefault”. (Client >> New >> DWORD (32-bit) Value >> name DisabledByDefault).
10. Now, simply double-click on it and set its Value data to “Zero.”
11. 11. Just like above, right-click on the Client button, then Go to “New,” and then Click on “DWORD (32-bit) Value.” and name it “Enabled.” (Client >> New >> DWORD (32-bit) Value >> name Enabled.)
    By double-clicking on it, set its Value data to “One.”
    Finally, Click on the OK button.

3. Through Power Shell Script

This solution only works by enabling the TLS version on TLS 1.2, but it can help you to solve error 10013. Check out the below given steps to know more.

6. Finally, Paste the Code and Run the script.

4. Allow TLS Protocols That Are No Longer in Use

In the final steps, we are going to enable the IIS Crypto GUI Application on TLS 1.2 and 1.1. Check out the below given steps to do so.

1. First of all, to download the application, you need to click on the “IIS Crypto GUI.”
2. You can easily launch the app by double-clicking on the IISCrypto.exe.
3. Ensure that the default directory for this app is the “Schannel tab”.
4. On the list, you will get two lists for the Server protocols and Client protocols sections; select TLS 1.0 and TLS 1.1 in both sections and click on Apply.

Wrapping Up

In conclusion, I have shared all about how to fix a fatal error occurred while creating a TLS client credential. The meaning of the error is that there is an imbalanced connection between the Client and server. You should note that this error can be due to many reasons like mismatched encryption protocols, invalid certificates, or sometimes network configuration issues as well. In this case, understanding the troubleshooting steps of it is needful. You can go through the above given fixes along with the detailed reasons and meaning of the error.
