open demo site: https://grapesjs.com/demo-mjml.html
drag an image
The image doesn't appear.
In browser console the following error appears: Failed to load resource: net::ERR_CERT_DATE_INVALID
If you open the image link in a new tab and replace http with https, the browser shows an error: Your connection is not private
Either update the source in blocks.js, from: 'http://placehold.it/' to 'https://via.placeholder.com/' (the rest of the parameters remain the same) or provide a way to specify the source of the image by parameters.
I think same issue happens also for grapesjs-preset-newsletter
