I use Atalassian for Jira successfully in IJ 8.1. In Maia build #10558,
when I "Test Connection" of the Jira server configured in Atlassisian just
like it is configured in 8.1, the Testing Connection dialog shows a thumb
flying back and forth, but it never completes, although I can cancel it. Is
this the same issue? Does the Atlassian plugin supposed to work in Maia?
