It’s very difficult to even guess unless you provide more details than “I tried something and it didn’t work”.
Exactly _how_ did you try to create the core? What are you trying to accomplish? What does the Solr log say on startup, there should be a message about where it starts looking for cores at least. Is this SolrCloud? If so you should _not_ be using the core adminAPI, use the collections API.
