Why, while using a dicated IP and a Cron command the Cron switches IP addresses on us?

Technut

Hello,

We are using WHMCS and its nightly billing function processes all billing using a CRON function, however this CRON causes our WHMCS to change [use] another IP address while doing so...... because we are using a WHMCS addon payment module that is licensed and locked to our IP address when the CRON runs it uses the servers MAIN IP address and not what our payment module's IP address is locked to. When this happens our payment module fails to work. As a workaround we have tried using the GET command but this causes other issues.

Our question is WHY does using a CRON switch IP addresses when it runs nightly in WHMCS, and how do we stop this from happening?

Thanks for reading this!
