Most IT departments and ISPs issue IP addresses using the Dynamic Host Configuration Protocol (DHCP). From time to time, your workstation’s IP address will change without warning. When it does, you’ll have to update your IP filter settings.
When ZooKeeper or Solr becomes “unreachable,” check the IP filters first.
Warning: SearchStudio Security Settings
Components of the SearchStudio will run on many different client computers, so the Solr endpoint cannot be shielded by IP Filtering. Solr’s IP Filter must be 0.0.0.0/0.
Therefore, SearchStudio enables Solr Basic Auth and creates two new Solr user accounts. Your SearchStax Admins will need Solr Basic Auth accounts of their own in order to connect to Solr.
