curl -Lv https://cloudflare.com/cdn-cgi/trace --proxy socks5://127.0.0.1<PORT> and curl -Lv https://cloudflare.com/cdn-cgi/trace --proxy socks://127.0.0.1<PORT>, I can access correctly. However, after setting proxy ports in Firefox or system proxy in Chrome, connections fail (only reproducible when using Socks5, Socks4 works perfectly). However, my environment includes applications that only support Socks5 connections. Are there any temporary workarounds?
