Sure, I tried again:

* Connection #0 to host www.sportnews.sa left intact
So your 301 redirect was not actually being followed and www.sportnews.sa was not working correctly.

This result is better although the twitter:url value is not valid.
Unfortunately although your robots.txt is correctly configured, your site still has issues and for some reason the validator and cards crawler cannot render a card. It doesn’t help that you have the twitter:card markup present at least twice (Yoast and Twitter Cards Meta By WPDeveloper are both including meta tags).
