I have added a physical machine Ubuntu 20.04 in Cloudmin with Virtualmin freshly installed, and made it a service host through Cloudmin Services, for DNS and DNS secondaries.
If I try to connect to that same cloudmin master from a Virtualmin for Cloudmin services client I get this:
After reading https://www.virtualmin.com/hosts/ I tried to reinstall the service machine, with Virtualmin installed through Cloudmin. I registered it as a service for DNS like before and got the same error message. I tried also from a Ubuntu 20.04 client, and same message again
