We used to have the Jira integration working, but it stopped working a while back and we haven't been able to use it since. I suspect it's related to the shift to using "atlassian accounts" for the jira cloud service we're using but I have no idea.
I've tried using the email address and the username itself, and I'm 100% sure the password and domain are correct, but I always get the error message:
jira reports the following error : Login failed
