Please follow below tips to troubleshoot the issue.

1.Go to “Computer Configuration -> Windows Settings -> Security Settings -> Public Key Policies -> Certificate Path Validation Settings" -> Properties -> Uncheck "Automatically update certificates in the Microsoft Root Certificate Program(recommended)" in the Network retrieval tab

2.In order to resolve this problem, the local trust relationship has to be created. This can be done by running the following PowerShell commands:

 $rootCert = (Get-SPCertificateAuthority).RootCertificate     
 New-SPTrustedRootAuthority -Name  "localNew" -Certificate  $rootCert  

After running the above commands, perform an IISReset on all servers in the farm.

3.Go to C:\Windows\System32\drivers\etc -> Add an entry in the host file for 127.0.0.1 crl.microsoft.com
