IPAM issues with DHCP in Windows Server 2016

Hello everyone. My name is Chris. I'm a student at Georgian College and I'm trying to resolve an issue with Windows Server 2016 and IPAM in one of my labs. I am in the IPAM > Server Inventory > IPv4 screen and have configured my manageability status to "Managed" and have toggled on DC, DNS and DHCP server options (as per the lab instructions). However, I keep getting a red x when I have DHCP toggled on. If it is toggled off, then I can get the green check mark in the IPAM access menu. I am unsure of how to troubleshoot this issue and I am frustratingly close to getting the lab done. I haven't been able to find any information online as to what the problem is, and am wondering if you know what is happening.

Thank you for your time, and have a good day.
