301 redirect to cloudflare link preview image not working

Hello,

I have Domain-A through Cloudflare and have a 301 redirect set up to Domain-B. When I share Domain-A on Twitter or Facebook (or use their card validator), the link/website preview does not show. When I share Domain-B directly on Twitter or Facebook, the preview shows.

What setting on Cloudflare is making to where the link preview from the redirect is not correctly populating?

Thanks!

My guess is that Facebook or Twitter is not following redirects.
