I am using Tridion sites 9, And I get "Failed to Query Elastic search" when I open the Targeting tab in CMS. XO service logs show some errors saying "Unknown host type". I feel it is not reaching elastic search at localhost:9200 but it is trying some other port.
About the tridion environment: CMS: Tridion 9 with Smarttarget capability installed Elastic search: version 5.6.16 with default settings (running on localhost:9200) along with ingest-attachment and analysis-icu plug-ins. Indexes from installElasticsearchIndexes.ps1 were also imported successfully. XO management service: Installed with and without ES host and port settings.
As I am getting an "Unknown host exception", I feel it is related to Elastic searching host and port setting registration in XO management service. Where can one see which host and port are registered for elastic search in the XO management service?
