Answer 1

Please perform the following troubleshooting：

1.In the Registry Editor, navigate to the following subkey, and then delete it: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\16.0\WSS\Services\Microsoft.SharePoint.Search.Administration.SearchService. Then, run the SharePoint Products Configuration Wizard again.

Note: It is recommended that you back up before deleting

2.Enable search admin timer job via powershell:

Enable-SPTimerJob job-application-server-admin-service

3.Update the account running Osearch15/Hostcontroller services using:

$password = Read-Host -AsSecureString
Set-SPEnterpriseSearchService -IgnoreSSLWarnings $true -ServiceAccount <domain\Account> -ServicePassword $password

4.Make sure the account you use to configure the application is a member of the WSS_WPG group and the group has full control over the following path: C:\Program Files\Microsoft Office Servers\15.0\Data\Office Server\Applications

5.Run following powershell to check if AdminComponents has value returned:

$sa = Get-SPEnterpriseSearchServiceApplication 'Search Service Application'
Get-SPEnterpriseSearchAdministrationComponent -SearchApplication $sa

If not, set as following:

$varInstance = Get-SPEnterpriseSearchServiceInstance -local
set-spenterprisesearchadministrationcomponent –searchapplication $varSearchApp –searchserviceinstance $varInstance

Instead of pointing SP the the VIP, point it to the AG Listener.
