Unknown Root Cause of Error

[JHFRDANALYSIS]

Error in my results query:  Unable to distribute to peer named 10.245.11.153 at uri=10.245.11.153:8089 using the uri-scheme=https because peer has status=Down.   

My query doesn't request anything for URI to be checked or returned so I don't know the root cause.  

I need to get a clean output with an error.  Any suggestions how to fix this?

Almost every search request is sent to your indexers and those indexers each have a uri.  This error message is generated when Splunk is no longer able to communicate with one of the indexers.  It could be because the indexer is down or because a network error prevents communication with it.  Verify all indexers are running and the search head can connect to them all.
