SharePoint 2013 Search: Unable to retrieve topology component health states. This may be because the admin component is not up and running
Problem:
SharePoint 2013 Search service application displays the error message “Unable to retrieve topology component health states. This may be because the admin component is not up and running.”
Solution:
After making sure the account configured to run search service & Search Service Host in the Services console, (Service.msc), Provisioned the Usage Application Proxy with PowerShell.
Open SharePoint 2013 Management Shell, and run these commands.
$UsageProxy = Get-SPServiceApplicationProxy | where {$_.TypeName -like "Usage*"}
$UsageProxy.Provision()
This is not working in 2019 environment. we tried to create new search as well but the same issue with the new search also.
exact the same issue below technet ” https://social.technet.microsoft.com/Forums/lync/en-US/1d4ba209-0f67-4a5a-ae71-a8d7c06e85e7/activating-search-topology-is-throwing-an-exception?forum=sharepointsearch ” and this too ” https://learn.microsoft.com/en-us/sharepoint/troubleshoot/security/configuration-to-support-kerberos-aes-encryption ”
and go to know that no recent GPO changes and no recent changes in service account too.
