Error: request has been blocked

We use Adobe Embed API for years and all was fine, untill today started getting the error: Connecting to 'https://documentservices.adobe.com/dcpreviewdropin/4.3.0_2.1537.0/private/printHelper_main.d5df691a.js.map' violates the following Content Security Policy directive: "default-src 'none'". The request has been blocked. Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback. The impact is that the download and printer options are gone.
