When using the Jira Service Management customer portal to search for solutions on a Confluence Knowledge Base, the error below is displayed:

"Something went wrong, either your query is invalid or we cannot contact the knowledge base."

The following appears in either the catalina.out or in the atlassian-jira.log:

In case the add-on does not enable successfully, try cleaning Confluence's plugin cache
