Fix fatal error when creating TLS client credentials

With the introduction of Windows 11 operating system, users rarely face problems while launching programs on their computers.

However, for programs that link to servers, users often encounter fatal errors when creating TLS client credentials on their systems.

Error messages are often not easy to interpret, especially when they are cryptic. But what's even more frustrating is when the error doesn't indicate what the problem is.

This tutorial is designed to help you fix fatal errors that occur while creating TLS client credentials without losing your files, documents, and other data.

What are TLS client credentials?

Transport Layer Security (TLS) is a protocol designed to provide secure communications over the Internet through end-to-end encryption, integrity proof, and authentication.

After establishing a TLS connection, the server will provide the certificate to the client. The client then verifies the server's identity by checking an Internet security protocol called client-side TLS.

Why do errors occur when using TLS client credentials?

The reason behind this error is that the program is a client that needs to connect to the server. Although the internet works fine, the client cannot decipher the code sent by the server.

This indicates a problem with the protocol. The error statement also points to the TLS encryption protocol.

Need to decrypt some encrypted information. The challenge is not knowing how to get the data back into a readable format.

Many times, this information is stored in the system registry of your Windows computer. Mentioned below are some possible workarounds you can try to fix this error.

What should I do if a fatal error occurs while creating TLS client credentials?

1. Enable TLS 1.0 and 1.1 protocols

1. Press the Windows R key and enter # in the Run dialog window ##inetcpl.cpl and press. Enter
In the Internet Properties window, click the
2. Advanced tab.
From here, check
3. Use TLS 1.0 and Use TLS 1.1.
Then, click Apply and
4. OK.
Restart the device and see if the error persists.

Enabling TLS 1.0 and 1.1 protocols should resolve this issue. However, if it doesn't work for you, move on to the next solution.

2. Run the Registry Editor

Press the
1. Windows R key, type regedit, and then click Enter.
At the User Account Control prompt, click
2. Yes.
In the Registry Editor, navigate to the following location:
3. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client<strong></strong>
Go to the right pane, right-click an available space and click New, then
4. DWORD (32-bit) Value.
Name the value
5. DisabledByDefault.
Double-click the value and in the pop-up window, enter
6. 0 for Value Data, and then select OK.
In the same way, create another value named Enabled and set the
7. Value data to 1.
Finally, exit Registry Editor and restart your PC.

The Windows Registry is an important tool that helps you change your computer settings. The Registry Editor is used to modify data such as file paths, window titles, or other key operating system settings.

The method used in this tutorial should be sufficient to fix a fatal error that occurred while creating TLS client credentials. The internal error status is 10013 Problem.

TLS can sometimes be a very buggy problem, and if you really don't need it, you can disable it all to stop it from causing any problems.
