Otherwise, try to go back.

When I posted the same in OpenQA the Repoowner suggested to take it up with AutoSPARQL forum. Please help me in solving this issue.

That SOLR Server does not exist anymore, you need to set up your own. However there will probably be further problems, as we don't maintain the project anymore.
