This error happens when you mistakenly import a certificate that’s not self-signed into the Local computer’s trusted authority store.

To fix this issue you will have to use the following powershell cmdlet on all the servers that are showing the error
  • Get-Childitem cert:\LocalMachine\root -Recurse | Where-Object {$_.Issuer -ne $_.Subject} | Format-List * | Out-File “c:\computer_filtered.txt”
  • Then type the command
  • Notepad C:\computer_filtered.txt
  • The command will open notepad file with the certificates details in it.
  • Take a note of all certificate’s thumb print number and open your MMC console
  • Click File -> add the Certificate then choose Local computer
  • Navigate to “Trusted Root Certification Authority” store

Check the certificate that their thumb print were shown in the Txt file and remove to the Intermediate Certification authority store.

If you have many certificates in the Trusted root store, you can manage the view and choose “Issued by” and then click on the certificate that the “Issued to” and “Issued by” do not match
