But I get:
XMLHttpRequest cannot load https://ashwinatmts.atlassian.net/rest/auth/1/session. Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://localhost:5551’ is therefore not allowed access. The response had HTTP status code 403.
Given this this response, I don’t know if this is even possible.
