A fatal error occurred while creating a TLS client credential.
A fatal error occurred while creating a TLS client credential. This error is usually caused by the following reasons:
The error Event ID 36871: A fatal error occurred when generating a TLS client credential has been triggered by the monitoring program. 10013 is the internal error code. You’ll discover why this is occurring and how to fix a catastrophic error that occurred when generating a TLS client credential in this post.
When establishing a TLS client credential, a catastrophic error occurred.
Start Event Viewer by logging in to the Windows Server. Select Windows Logs > System from the drop-down menu. Event ID 36871 will appear as an error. When establishing a TLS client credential, a catastrophic error occurred. 10013 is the internal error code.
What causes this problem and how can we fix it? A catastrophic error occurred when generating a TLS client credential. What is the internal trouble code 10013?
Examine the protocols for Transport Layer Security.
Schannel is a Security Support Provider (SSP) that supports the Internet standard authentication protocols Secure Sockets Layer (SSL) and Transport Layer Security (TLS).
Nartac Software’s IIS Crypto GUI is available for download. Start the program once it has been downloaded.
TLS 1.0 and TLS 1.1 are unchecked for Server Protocols and Client Protocols.
When we choose Best Practices, the Server Protocols and Client Protocols TLS 1.0 and TLS 1.1 are enabled. The event error will not appear after a reboot. We solve the issue by doing so, but we also enable the deprecated protocols. We don’t want it to happen.
So, how can we maintain TLS 1.0 and 1.1 unchecked (disabled) without getting the fatal error TLS client credential 10013?
Status of Transport Layer Security protocols
See a list of security protocols, as well as when they were first published and their current state. Only TLS 1.2 and TLS 1.3 are authorized at the time of writing.
| Protocol | Published | Status |
|---|---|---|
| SSL 2.0 | 1995 | In 2011, it was deprecated. |
| SSL 3.0 | 1996 | In 2015, it was deprecated. |
| TLS 1.0 | 1999 | In 2020, it will be deprecated. |
| TLS 1.1 | 2006 | In 2020, it will be deprecated. |
| TLS 1.2 | 2008 | Approved |
| TLS 1.3 | 2018 | Approved |
A catastrophic error happened when generating a TLS client credential, and here is the solution.
Now that we’ve collected all of the information, we’ll execute the script to activate TLS 1.2 on the machine. We’ll examine the Event Viewer after a reboot. There should be no mistakes.
PowerShell should be run as an administrator. Download and execute the Enable-TLS1.2.ps1 PowerShell script from PowerShell. Another option is to use the PowerShell script below.
-Force | Out-Null New-ItemProperty -path ‘HKLM:SOFTWAREWOW6432NodeMicrosoft.NETFrameworkv4.0.30319’ -name ‘SystemDefaultTlsVersions’ -value ‘1’ -PropertyType ‘DWord’ -Force | Out-Null ‘TLS 1.2Server’ is an acronym for ‘Transport Layer Security’. -Force | Out-Null New-ItemProperty -path ‘HKLM:SYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProtocolsSCHANNELProto -name ‘Enabled’ -value ‘1’ -PropertyType ‘DWord’ -Force | Out-Null New-ItemProperty -path ‘TLS 1.2Server’ HKLM:SYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2Server’ -name ‘DisabledByDefault’ -value 0 -PropertyType ‘DWord’ -Force | Out-Null New-Item SCHANNELProtocolsTLS 1.2Client’ -Force | Out-Null New-ItemProperty -path ‘HKLM:SYSTEMCurrentControlSetControlSecurityProviders’ SCHANNELProtocolsTLS 1.2Client’ -Force | Out-Null New-ItemProperty -path ‘HKLM:SYSTEMCurrentControlSetControlSecurityProviders HKLM:SYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS 1.2Client’ -name ‘Enabled’ -value ‘1’ -PropertyType ‘DWord’ -Force | Out-Null New-ItemProperty -path ‘HKLM:SYSTEMCurrentControlSetControlSecurityProvidersSCHANNELProtocolsTLS
Run the script by pasting it into PowerShell ISE.
The Windows Server should be restarted.
Start the Event Viewer program. Click System after expanding Windows Logs. “Event ID 36871: A catastrophic error occurred when establishing a TLS client credential,” says the error message. The message “The internal error status is 10013.” no longer appears.
How did it go for you?
Conclusion
You now understand why a fatal error occurred when attempting to create a TLS client credential. 10013 is the internal error code. Configuring TLS 1.2 on the Windows Server is the answer to this issue. After that, the Event ID 36871 problems are no longer visible in Event Viewer.
