IPAM 2020.2.6 Windows 2019 DHCP server supported? error 183

Trying to add a Windows 2019 DHCP server to IPAM gives the following error:

"Test failed - Exception impersonating user, error code: 183"

The user can log on the server and manage DHCP.
No firewall is blocking communication between Orion server and DHCP servers.

But on the page in Orion where you add a DHCP server, the top states current windows DHCP server versions supported and 2019 is not included

Does IPAM 2002.2.6 support Windows DHCP Server 2019?
If so, what is needed to manage Windows 2019 DHCP server in IPAM?
