Url without www is not working

When I enter poplar.care without www, the website does not load, shows a message ‘This site cannot be reached’ I have a page rule setup in Cloudlfare that should redirect poplar.care to www.poplare.care Any idea why this is happening and how to fix it?

When I visit poplar.care I do get redirected to the www URL. I would try in an incognito window to see if it still happens.
