If you use Tachiyomi to read manga, you might have seen the error “Failed to bypass Cloudflare” when loading certain extensions. This happens when the source website’s security system (Cloudflare) blocks Tachiyomi’s request. Here’s what causes it — and how to fix it fast.
Why the “Failed to Bypass Cloudflare” Error Happens
Cloudflare protects websites from bots and suspicious traffic. When Tachiyomi tries to access a site, Cloudflare may block or challenge it if:
- The extension or app is outdated, using old bypass methods.
- Your cookies or cache are corrupted.
- Your IP or region looks suspicious or changes too often.
- You’re using a VPN or unstable proxy IP that Cloudflare flags.
- The site’s Cloudflare settings are extremely strict or recently updated.
In short, Cloudflare thinks your connection isn’t a normal browser request — and stops Tachiyomi from loading content.
Quick Fixes That Work
- Update Tachiyomi and the extension Outdated versions can’t handle Cloudflare’s latest challenges. Go to Extensions → Updates and install the latest version.
- Clear cache and cookies In Settings → Advanced, clear WebView data and cookies. Restart the app.
- Change User Agent In Settings → Advanced → Default user agent, copy your mobile browser’s user agent and paste it here. This helps Tachiyomi mimic a real browser.
- Use WebView to pass the challenge Tap “Open in WebView,” solve the CAPTCHA if shown, and go back. This stores the correct Cloudflare cookie.
- Switch networks or use a clean IP Sometimes Cloudflare blocks your IP. Switching to mobile data or a more stable proxy often works. If you frequently access overseas manga sites, using IPFLY’s residential proxy with real, clean IPs can reduce Cloudflare blocks significantly.
When the Error Keeps Appearing
If it still says “Failed to bypass Cloudflare” after trying the above:
- The site might have changed its protection layer. Wait for the extension to update.
- Your IP reputation may be poor — shared or flagged IPs get blocked easily. A static, verified proxy (like IPFLY’s static residential IPs) can make requests look more trustworthy.
- WebView is outdated — update Android System WebView and Chrome from the Play Store.
How to Avoid It in the Future
- Keep Tachiyomi, extensions, and WebView updated.
- Avoid frequently switching VPNs or unstable proxies.
- Use IPFLY’s global proxy nodes to maintain a consistent IP region when accessing different manga sources.
- Clear cookies if a site suddenly stops loading.
Summary
“Failed to bypass Cloudflare” in Tachiyomi usually means Cloudflare suspects your connection. The fastest fixes are updating, clearing cache, changing user agent, or switching to a stable IP. For users who often read manga from different regions or manage multiple sources, IPFLY’s residential and static proxies provide clean, stable IPs that help keep Cloudflare happy — so Tachiyomi runs smoothly without repeated errors.
