Thanks for sharing, glad the issue is resolved. The specific issue only affects 4.15.0.0 and older releases, this issue is however fixed in 4.15.1.0.
After adding hosts you may actually revert the original sshd configuration.

In case you've attached them to your mail, the ML may not allow large attachments. Are you using ACS with basic zone on Ubuntu 20.04, both as mgmt server and KVM host? In which case you may want to tail/investigate the logs on both the management server and the KVM agent(s).
