Please provide more details about what you are trying to do.

It seems like you already have an engine. Can't tell if it's a hosted
engine or not. Is it?

It seems like the host you are trying to deploy is/was already managed
by your engine. Is it?

Generally speaking, we do not allow "converting" an engine to a hosted
engine nor doing 'hosted-engine --deploy' on a host already managed by
the/an engine. For the former, please check [1]. For the latter, you
should first remove the host from the engine. [1] is very old, and some
details are different today, but the principles remain. I recommend
trying this first on an isolated test env before doing on production.

BTW, the above does not explain your failure. Your specific failure is:

JsonRpcNoResponseError: [-32605] No response for JSON-RPC
Host.getCapabilities request.

To me it seems like 'hosted-engine --deploy' managed to connect to the
engine (not sure which, existing or one created in new hosted-engine vm)
but fails to get the list of clusters, probably because the engine fails
to connect to one or more hosts. Can't see that in the attached engine.log
btw - either it's from the wrong machine, or wrong time/timezone, something
like that.
