Test network connectivity

Follow the steps to test network connectivity and perform a certificate verification.

Two test are required to validate connectivity:

Network connectivity test validates that application servers can communicate to TCP port 443 for all Zuora Akamai IP addresses. If you use allow lists for outbound communication, you must verify that your systems can connect to all of the new Zuora servers.
Certificate verification test validates that the certificates were imported correctly and customer applications can establish SSL connections based on the new EV SSL certificates.

Test network connectivity
1. Using a Windows or UNIX system, telnet to TCP port 443 on each IP address listed.
  If the telnet connection is successful to all IP addresses listed above, then connectivity has been verified.
2. If a connection cannot be established to any of the IP addresses listed above, then your network team must add those specific IP addresses to the allow list.
Test the certificate import
1. Identify the certificate store that your application uses.
2. Use the appropriate tool for your environment (for example, keytool, openssl, Windows Certificate Manager, etc) and verify that the Root Certificate labeled VeriSign Class 3 Public Primary Certification Authority - G5 exists in the store and is trusted.
