We have configured JIRA to be able to add defects through our Test Rail Project. However, when we wish to view the defect in Test Rail, we get this error: Plugin “Jira_REST” returned an error: Invalid HTTP code (404). Please verify the address of your JIRA installation in the configuration settings and that TestRail can reach your JIRA server.
We are using JIRA REST as the plug in and the configuration settings look correct. I am at a loss of what to do next.
