The Preview Mode of Google Tag Manager is not working.
When you visit the site, the preview dialog does not appear - and the gtm.js request receives a 404 error while preview mode is active.
I have tried everything on the internet that people suggests to enable the preview dialog box, but it still does not appear. I am 99% sure that it is because of an implementation issue this library introduces.
