PolymarketHad the same infinite-loading on Polymarket (site works a few min then gets stuck). Two things that helped me: 1) Disable HTTP/3 (QUIC) in your browser. Brave: brave://flags/#enable-quic → Disabled → Relaunch. Chrome: chrome://flags/#enable-quic. Firefox: about:config → network.http.http3.enable → false. It's harmless + reversible — just forces the browser to use TCP instead of HTTP/3. 2) When it's stuck: a fresh browser profile, or clearing cookies+cache for polymarket.com, or just waiting ~5 min also gets you back in (looks like Cloudflare rate-limiting heavy sessions). Note: disabling QUIC won't fix everyone — if a fresh profile already loads fine for you, your issue is more the session/rate-limit side (Polymarket/Cloudflare). But QUIC-off is a 30-sec test that costs nothing and helped my case a lot.
