Unable to locate Vimeo content using Video Block

Can anyone help me with this issue?

Every time I pasted a normal URL from my Vimeo video into my Squarespace video block, it kept saying:"Unable to locate content" then it wipes the URL blank.

I have removed and re-inserted the video block again and again to no avail.

Any help is much appreciated,
Ronald

EDIT: the problem lies with my Vimeo setting. I changed the embed permission to 'Anywhere'.
