Purpose When trying to access the Jira section in Salesforce, an error is shown. Reviewing the console/HAR file, the following error can be seen: Error Message has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header has a value 'https://backroads--uatsandbox.lightning.force.com' that is not equal to the supplied origin Answer This issue is related to  CORS policy . In the HAR file, the original URL is different from what is shown in the error. To make sure that Salesforce returns the correct CORS information on the HTTP header (so that the browser will block the request), you need to allow the  origin  in the request header: Go to  Setup  > search for  CORS  and click it. Under  Allowed Origins List , select  New  and enter the origin URL pattern. If performing the steps mentioned above does not resolve the issue, contact  Appfire Support  to investigate this further.
