access JIRA via Check Point's Capsule Workspace mobile browser

Dear team,

We would like to access JIRA core system via Check Point’s Capsule Workspace mobile browser but we are facing issues rendering the jira pages.

According to Check Point support team the issue occur because the below URL is included in the application source code and in order for the browser to render the page correctly, it has to download the file from an external public server:

Could you please let us know if there is a proper way to include this file (and any other critical files fetched from external serves) within the local files on our server and then change all references in the code to point to the local file?

Thank you in advance.
