title: GraphQL Server Cannot Be Reached Status Code 500
body: <p>When attempting to use GraphQL Playground, it seemed like a cached version of schema.graphql was being referenced. So, I went ahead and ran <code>php artisan cache:clear</code>, which resulted in an error of "Server cannot be reached" and '"error": "Response not successful: Received status code 500"'.</p>
  
  <p>I tried running <code>php artisan cache:config</code>, but that didn't resolve the issue.</p>
  
  <p>I'm expecting to be able to connect, but it doesn't seem to want to connect. Connecting wasn't an issue prior to running <code>php artisan cache:clear</code>, just that any attempts to write a query seemed to reference the old schema.graphql, which isn't expected.</p>
