Connect EA conector to Jira

[Lucía Manescau]

I'm trying to connect EA with Jira with the Add-In "EA connector for Jira". I follow all the instructions, I have Jira well configured (I'm sure about it because other applications can connect to Jira) but when I tried to do the mapping, put the user and password, and an error is shown telling me that I must enter the user and password (that I already entered), and after that message, the next exception is show.  I'm using EA v.7.5 and Jira 5.0. Someone can help me to be able to connect to Jira, please?

Exception:
