It's the engine that needs to open an SSH connection to the host calling it by its hostname.
So please be sure that you can SSH to the host from the engine using its hostname and not its IP address.
Till hosted-engine hosts were simply identified by their IP address but than we had some bug report on side effects of that.
So now we generate and sign certs using host hostnames and so the engine should be able to correctly resolve them.

It's cause the setup didn't complete.

It's cause the setup didn't complete.

First step is to clarify what went wrong in order to avoid it in the future.
Than, if you want a really sanity environment for production use I'd suggest to redeploy.

So
 hosted-engine --vm-poweroff
empty the storage domain share and deploy again
