Error Unable to retrieve topology component health states. This may be because the admin component is not up and running

Question

After an outage and after bringing up all the services back online.

The Search Server Application : Search Admin cant find all the search application topology.

It's showing error :

Unable to retrieve topology component health states. This may be because the admin component is not up and running.

Looking at the event logs i can see error:

A failure was reported when trying to invoke a service application: EndpointFailure for http://XXXX/ccc/SearchService.svc

When I click on the link endpoint it works.

Do I need to re-provision this for it to work or the services needs to be rebooted in a particular sequence?

There is a 2 web server , 2 app server and one OWA

Can you check whether the WSS Usage Application Proxy is stopped? If so, use the following PowerShell to start it, then try accessing the Search Service Application again: $WUP = get-spserviceapplicationproxy | where {$_.typename -like "Usage*"} $WUP.provision() — Andy Dawson, May 03 '16 at 13:10
Just to clarify, there are two commands beginning '$WUP' shown above; these should be run as separate commands, not run together as they are shown. — Andy Dawson, May 03 '16 at 13:13

I encountered the same error in SP2016, in my Search service Administration page , I have seen this error in admin page

Unable to retrieve topology component health states. This may be because the admin component is not up and running

After that i tried to bring the Admin component by various tricks, tried to check whether all app pool is running .

and ran IIS reset and that does not help.

I tried to create another Search service Application , that too did not help.

after that I noticed that "SPSearchHostController" service was not running fine.

Then I restarted the machine , that finally helped the "SPSearchHostController" made to Automatic Mode and up and running.
