Error: Unable To Fetch Request Token

Issue

When I try to authorize the Jira connection, one of the following errors appear:

• ERROR: "exceptionType":"java.lang.RuntimeException", "exceptionMessage":"Unable to fetch request token."
• ERROR: "Request token request failed with response: "oauth_problem=consumer_key_unknown""
• ERROR: "oauth_problem=signature_invalid"

Environment

Connector: Jira

Resolution

Recreate the application link.

Also, see the following Jira troubleshooting guides:

• Application Links Troubleshooting Guide
• OAuth Troubleshooting Guide
• OAuth error oauth_problem=consumer_key_unknown
• OAuth error oauth_problem=signature_invalid

Cause

There are a few possible causes for these issues:

• There is duplicate data in the database causing it to use a different consumer key.
• The application link is only configured in one direction. For example, Confluence is linked to Jira; but Jira does not have a reciprocal link to Confluence. This can be caused by a misconfigured network where one application server cannot reach the other over the connector port.
• The application URL of the link does not match the URL that the remote application is reporting.
