Refused to display 'url' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'

I faced the same error when displaying YouTube links. For example: https://www.youtube.com/watch?v=8WkuChVeL0s

I replaced watch?v= with embed/ so the valid link will be: https://www.youtube.com/embed/8WkuChVeL0s

It works well.

Try to apply the same rule on your case.

You cannot display a lot of websites inside an iFrame. Reason being that they send an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page. This is a security feature to prevent click-jacking. Some details at How to show google.com in an iframe?

I was facing this issue in Grafana and all I had to do was go to the config file and change allow_embedding to true and restart the server :)
