You need to include “https://” wherever you have included a URL in your tags:
<meta name="twitter:image" content="latency.gg/img/noticias/Liquid_ficha_a_KonKwon.jpg" />
should be
<meta name="twitter:image" content="https://latency.gg/img/noticias/Liquid_ficha_a_KonKwon.jpg" />
Additionally, I would go ahead and remove the rules from https://latency.gg/robots.txt to avoid any issues that might arise there (you’re actually blocking Twitterbot from reading all of your content except for the images).
