My problem was due to my CloudFlare SSL set to minimum TLS 1.3. When I used Twitter Card Validator to test my cards, I would get unknown error and cards would not show up. I found solution here. Issue was that Twitter is (still) not supporting TLS 1.3 and I had to degrade to TLS 1.2. Immediately my cards were displayed.
