Twitter Cards Fetching Error



Hi, I’m trying to display the Twitter Cards.
Some URLs display Card correctly, but others do incorrectly.

On the Cards Validator, The URLs incorrectly displaying Card show Error message below:
ERROR: Fetching the page failed because the fetcher cannot resolve the address.

Furthermore, sometimes correctly displaying URLs is whitelisted, sometimes the URLs show fetch error.

anyone knows how to solve?

Thank you.
