While accessing the Rally Saas instance by sending the API request to Rally customers were getting the "403 Forbidden" error from the Rally server.
Based on the API Logs we have found that the "403 Forbidden" throws by the server. ( Usually, this happens when the client is not permitted access to the resource despite providing authentication such as insufficient permissions of the authenticated account.)
This unexpected behavior happened with Rally Saas Instance using API-> was it down/connection issues.
Release : SAAS
Component : AGILE CENTRAL
If the issue still persists please create a support case to the Rally support team with the screenshot of the error and along with API logs
