1. We can then check the registry Key for the Public Key that comes with the Installer at the following path.
Key Name: ServiceNowCertPublicKey
 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\Credential Providers\{0780AF60-65C2-4718-942D-E0C56E89EF9B}] 
2. Compare that public key in Windows Registry with the Public Key from the Certificate on the Instance and we could see that they are different.
    Getting Public key from Instance:
   * enter url  i.e https://instancename.service-now.com in IE Browser 
   * click on lock icon on the browser bar -> View certificates -> Details -> Public Key -> copy the key 
   * put the key in the notepad and compare with the key from registry.
3. Copy the Public Key from the Instance
4. Add or replace the existing key in Windows Registry with the key from Instance. As this field allows multiple public keys.
5. Then re-launch the Application and confirm that it worked.
6. You can then export that registry key and import it on other affected Windows host.
