I am trying to get a session cookie from:
POST
https://xxx.atlassian.net/rest/auth/1/session
{"username":"aaaa","password":"bbbb"}
I am pretty sure that the provided credentials are correct - I can login with them in the web interface. However the call made with Postman always returns:
{ "errorMessages": [ "Login failed" ], "errors": {}}
There is no response header that would give any more information why it fails.
What could be the reason? I was thinking that maybe it is catpcha, but I cannot check that, as I always get redirected to https://id.atlassian.com when I try to access the Jira login page directly.
