Created brand new SharePoint 2019 Farm using AutoSpInstaller. In central Administration all Search services are showing green. But Search is not giving any results. ULS log shows "All query processing components are in 'Failed' status." and "Query processing component 'net.tcp:///QueryProcessingComponent1/ImsQueryInternal' changes its status to 'Failed'"

Following steps also done

1. Cleared Cache and rebooted servers (app and wfe)
2. Checked all Search Application Services are running
3. Restarted Search Host Controller service net stop OSearch16 net start OSearch16
4. Checked all Search services on App server running
5. Checked search tcp ports 808, 32843, 32844
6. Reset index and re-crawled source. Showing success count in crawl log

Any pointers will be appreciated
