Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from data theft to site defacement to distribution of malware.

If a web server has set a CSP, it is not possible to replace frameworks/libraries by LocalCDN. In this case you have to disable LocalCDN for this website.
