All right guys,
Here the strange behavior caused by a oEmbed/Vimeo (it's also true with a simple iframe code copied from the share button) on my webpage. First, the following webpage https://theprintatelier.com/ will rendered perfectly, showing an oEmbed video from Vimeo, there will be no error, everything looks fine.
Then, when you do a GET Request with Postman, or with Fetch As Google or any other SEO tools, I will get an 403 Forbidden response, which break any chance of the site being referenced in any search engine.
I know the root of the problem is the Vimeo Video on the page, when I take the video off the page, Bang! I get a 200 OK response from the HTTP request.
Do you guys have any idea to fix that strange problem? Or what can cause it?
Thanks :)
