Hi @cixhebus,

Good progress getting Squid working in transparent mode! The issue with Discord likely comes from certificate pinning — even though you've excluded *.discord.com, Discord also uses domains and CDN subdomains. These still get SSL-bumped, causing the page to fail.

Quick fixes:

• Check your browser's developer tools (Network tab) to see which domains fail.
• Add all related Discord domains to your "SSL no-bump sites" list.
• Test by temporarily disabling SSL bumping for Discord — if it loads, that confirms the cause.
• If issues persist, consider explicit proxy mode instead of transparent; it's more stable for HTTPS traffic

.
Transparent proxies often break pinned or HSTS-protected sites — bypassing them for services like Discord is usually the cleanest solution.
