Having the same issue. Tried both solr cloud and standalone. For the standalone configuration, I am able to run solr, create core, import data via DIH, and start making queries. Everything works fine until I re-start it. I am on Amazon Linux AMI, tried Solr 6.0.1, 6.3.0, 6.4.1. All failed to restart. And yes, I only have one core, and started solr from the same location sudo service solr start. After restart, I can not find any core in "Core Admin". But I can select my previous core in "Core Selector". Only that after selecting it, an error message "Connection to Solr lost" shows – user2868104

Are you sure the first Solr start and the second used the same home? If you started the first time with bin\solr start -e examplename , then your home might be in a different location depending on the example chosen. Restarting Solr without example information uses the default server location.

Try starting solr with bin\solr start -s path_to_home and see if the cores are found then.

Do You have multiple cores in your solr-Installation?

If yes, check the core.properties for duplicate "name"-Attribute.

Also check your solr log files for errors regarding CorePropertiesLocator.
