CORS error when connecting on-premise JIRA to Zoho Desk

CORS error when connecting on-premise JIRA to Zoho Desk

Hi,

I'm trying to integrate my on-premise JIRA application with my Zoho Desk account. When I tried to create an Application Link in JIRA, I set the application link to " https://desk.zoho.com/" as documented and clicked Create new link, but I got the following error in a pop-up: " No response was received from the URL you entered - it may not be valid. Please fix the URL below, if needed, and click Continue."

I checked the Network tab in the Chrome Developer tools for the response returned by Zoho when JIRA tries to create the application link and found the following error (screenshot attached):

  1. desk.zoho.com//rest/applinks/3.0/manifest.json?_=1498133114198
  2. Failed to load resource: the server responded with a status of 404 (Not Found)
  3. listApplicationLinks:1
  4. XMLHttpRequest cannot load https://desk.zoho.com//rest/applinks/3.0/manifest.json?_=1498133114198. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://jira.elementn.com' is therefore not allowed access. The response had HTTP status code 404.
  5. batch.js?agile_global_admin_condition=true&healthcheck-resources=true&jag=true&jaguser=true&locale=…:349
  6. Unable to retrieve remote Manifest. Try again using CORS

Is there a way to set CORS in Zoho Desk?
