We want to OAuth for JIRA rest API authentication. But we are getting error which accessing token.

[Abhishek Barnwal]

We are using below doc to generate Oauth Token https://developer.atlassian.com/server/jira/platform/oauth/

We are getting below error after using java -jar OAuthTutorialClient-1.0.jar requestToken, We are using Okta as SSO. We also tried to use same steps provided in local jira instance but here its working fine.
