All the scripts and executables in the Site24x7 Windows Server Monitoring Agent are digitally signed.
To verify the digital signature, we compare the certificate name and the serial number of the digital signature associated with the script with our certificate's signature name and serial number.
When trying to execute a signed script or executable, the system will contact the IP addresses hosted by the Online Certificate Status Protocol Responder, ocsp.sectigo.com, which is the signing certificate provider, to verify the revocation status of the certificate.
Therefore, the above-mentioned domain should be allow listed after successfully adding the server monitor.
