Comments
 
Based on my research the issue can be caused by corrupted certificate data on the server. I suggest you try the following steps to test the issue:

1. Backup and delete the contents of the following folders:

C:\Windows\System32\config\systemprofile\AppData\LocalLow\Microsoft\CryptnetUrlCache\Content
C:\Windows\System32\config\systemprofile\AppData\LocalLow\Microsoft\CryptnetUrlCache\MetaData

2. Backup and delete the certificates listed under "Certificates" key:

HKEY_LOCAL_MACHINE\Software\Microsoft\SystemCertificates\AuthRoot\Certificates

Then restart the server to check the result.
As per ME976235, this issue may be caused by conflicts with antivirus and other security programs or if your currently logged on user account does not have sufficient permissions to write to the temporary (Temp) folder. The article provides a workaround.
As per T734018, The automatic Root Certificates Update component downloads a cabinet (.cab) file to the temporary directory on the local computer, extracts the contents of the file, and then updates the root certificate list. The correct permissions must be applied to the temporary directory in order for the cabinet file to install correctly. This event may be recorded if the permissions for this temporary directory are not right. See the article for more details.
