Dspace not running

[Precious Kapfunde]

Good day everyone,

I am kindly requesting assistance as I am experiencing some challenges with DSpace. I installed DSpace on a Bluehost server, and after completing the installation, it is not running. Below are the error logs.

[DSpace Technical Support]

Hi,

The error you are seeing is one that can occur when Solr is unavailable or down.  See this bug ticket: https://github.com/DSpace/DSpace/issues/9217

So, make sure that Solr is running *before* you start up Tomcat.  You also may want to look to upgrade in the future, as this error no longer will occur if you are running 7.6.2 or 8.0.  (That said, you should be able to avoid it by just starting up Solr before you start up Tomcat).
