Content Security Policy blocks loding of iframe cal in IPFS

[nuke-web3]

Content Security Policy: The page’s settings blocked the loading of a resource at [https://calendar.google.com/...

For sure works for a local dev server as well as the hosted site!

...but does not for the gateway IPFS preview on pinata for example.
Must be the preset meta tag for this is somehow wrong...
