Symptoms

When accessing a project in JIRA and clicking on the 'Source' tab, the following error is shown in the GUI:

Error in remote call […] Received status code 403 (Forbidden)

Cause

Either the logged in JIRA user doesn't have access to Fisheye or the Application Link between JIRA and Fisheye is configured with Basic Access such that the user doesn't have permissions to the Fisheye data (repositories).

Resolution

Add the JIRA user (using the same username) to Fisheye. If the username already exists in Fisheye, remove all the authentication methods (Trusted Application, Oauth, Basic Access) in the Application Link and recreate it again.
