I have configured JIRA integration in my self hosted TestRail instance but I still cannot see JIRA details from TestRail.
The server that testrail runs on has access to my (also self-hosted) JIRA server (6.x). I confirmed that using curl --user user:pwd https://jira.domain/net/browse/AAA-1000 for example. Using curl like that I get a response from the JIRA Server.
However, if I try to, for example, hover the mouse over the JIRA ticket number in my test case result, I get the error:
Invalid HTTP code (400). Please verify the address of your JIRA installation in the configuration settings and that TestRail can reach your JIRA server."
To check if it was a specific problem with the REST API I did
curl --user xxx:xxx https://jira.xxxxxxx.net/rest/api/2/search?jql=issue=1457201&maxResults=10
and I also get results.
Any idea what could be wrong?
