Discord is a popular community but when I enable Super Bot Fight Mode then Cloudflare blocked Discord bots to render OG images.
You can add bypasses now for superbot fight mode unless you have not been migrated to custom firewall rules. From my understanding allnusers should be but i may wrong. Just allowlist the useragent or i.p or something along these lines.
Discord needs to apply for this also officially which i doubt theyll do. Just modify the custom rules like i said first.
