Privately hosted vimeo video not showing on page

Firstly apologies if this is the wrong group to post this question.

I cannot seem to preview or play privately hosted videos from vimeo into my Webflow page. I have set parameters on vimeo to embed only in selected domains. But I am having no luck. I am presuming its settings in vimeo that’s causing the problem. But I don’t know what the solution is.

I have put in my sites .webflow.io domain address as one of the domains allowed to embed this video, and also my website domain address itself.
