If you’re a manga lover, Tachiyomi is your go-to—free, open-source, and packed with thousands of titles from global sources. But nothing kills the vibe faster than seeing “Failed to bypass Cloudflare” pop up when you try to load a chapter. You refresh, switch sources, and even reinstall the app—yet the error persists. For Tachiyomi users, this frustration is all too common.
Cloudflare’s security measures are designed to block bots, but Tachiyomi (and its extensions) often get flagged as “suspicious” by mistake. Failing to bypass Cloudflare means missing out on your favorite manga, and generic fixes rarely work. In this guide, we’ll break down why the bypass fails, common mistakes you’re making, step-by-step solutions to fix it, and how a tool like IPFLY ensures you never see that error again. Whether you’re a casual reader or a die-hard manga fan, this guide will get your Tachiyomi running smoothly.
Why Does Tachiyomi Fail to Bypass Cloudflare?
To fix the problem, you need to understand the root cause. Cloudflare is a web security platform used by most manga sources to block bots, scrapers, and malicious traffic. Tachiyomi works by scraping these sources, so Cloudflare often flags it as a bot—triggering the “bypass failed” error. Here’s why your bypass attempts keep failing:
Cloudflare’s Core Checks (That Tachiyomi Struggles With)
Cloudflare uses 4 key checks to distinguish bots from humans—if Tachiyomi fails any, the bypass fails:
JavaScript (JS) Challenge: Cloudflare sends a small JS code that real browsers execute. Tachiyomi’s default setup may not run JS properly, so it gets blocked.
IP Reputation: If your IP is shared, blacklisted, or from a data center, Cloudflare marks it as suspicious.
Browser Fingerprint: Tachiyomi’s default user-agent (a string identifying the app) is generic, making it easy for Cloudflare to spot.
Request Rate: Scrolling through too many chapters too fast triggers Cloudflare’s anti-bot systems.
Tachiyomi-Specific Issues
Even if Cloudflare’s checks are strict, Tachiyomi users often face avoidable mistakes that worsen the problem:
Outdated Tachiyomi app or extensions (old versions lack bypass updates).
Using free/overcrowded proxies (they get blacklisted quickly).
Disabling JS in Tachiyomi’s settings (directly fails Cloudflare’s JS challenge).
Overloading a single source with too many requests (e.g., batch-downloading 50 chapters at once).
Common Reasons You’re Failing to Bypass Cloudflare with Tachiyomi
Before diving into fixes, let’s pinpoint the most likely culprit for your “bypass failed” error:
Outdated App/Extensions
Tachiyomi and its extensions are regularly updated to counter Cloudflare’s new security measures. Using an old version means you’re missing critical bypass tools—Cloudflare detects this and blocks you.
Poor-Quality Proxies
Free or cheap proxies are shared among thousands of users, so Cloudflare has already blacklisted them. Even if they work once, they’ll fail within hours.
JS Execution Disabled
Tachiyomi’s default settings enable JS, but some users disable it to “speed up” loading. This is a death sentence for Cloudflare bypass—JS execution is mandatory to pass the challenge.
IP Blacklisting
If you’ve used Tachiyomi on public Wi-Fi or a shared network, your IP may have been flagged for spam or bot activity. Cloudflare blocks it regardless of the app you’re using.
Generic User-Agent
Tachiyomi’s default user-agent screams “bot” to Cloudflare. Without a custom user-agent that mimics a real browser (e.g., Chrome, Firefox), the bypass fails.
Step-by-Step Fixes for “Failed to Bypass Cloudflare” in Tachiyomi
Let’s fix the error with actionable steps—start with the simplest, then move to more advanced solutions:
Update Tachiyomi & Extensions (Critical First Step)
Outdated software is the #1 cause of bypass failures. Here’s how to update:
Open Tachiyomi → Go to “More” (bottom-right) → Select “Extensions.”
Tap “Update All” to refresh all manga sources (extensions often include bypass patches).
Check for Tachiyomi app updates: Go to “Settings” → “About” → “Check for Updates.”
Most users fix the bypass error just by updating—Cloudflare’s latest checks are already accounted for in new versions.
Enable JavaScript in Tachiyomi
Cloudflare’s JS challenge is non-negotiable—Tachiyomi must execute JS to pass. Here’s how to confirm it’s enabled:
Go to Tachiyomi “Settings” → “Advanced” → “WebView Settings.”
Ensure “Enable JavaScript” is toggled on (it’s on by default, but double-check).
Never disable this—even if you think it speeds up loading, it guarantees a bypass failure.
Use a Reliable Proxy (Enter IPFLY)
Generic proxies fail because they’re detectable. You need a proxy that mimics real human traffic—and IPFLY is perfect for Tachiyomi. Here’s why IPFLY fixes the bypass error:
How IPFLY Solves Tachiyomi’s Cloudflare Woes
Real Residential IPs: IPFLY’s proxies are sourced from real end-user devices (ISPs) in 190+ countries. Cloudflare sees them as “human users,” not bots—no more IP blacklisting.
JS-Friendly Routing: IPFLY’s servers support JS execution, so Tachiyomi can pass Cloudflare’s JS challenge seamlessly.
Global Coverage: If a manga source is geo-restricted (e.g., a Japanese source blocked in your country), IPFLY lets you switch to a local IP—bypassing both Cloudflare and geo-limits.
Low Latency: Unlike free proxies that lag, IPFLY’s servers load manga chapters quickly—no buffering while bypassing Cloudflare.
How to Set Up IPFLY with Tachiyomi
Setting up IPFLY takes 2 minutes—no technical skills needed:
1.Sign up for IPFLY and choose a residential proxy plan (best for bot detection avoidance).
2.Get your IPFLY proxy details (IP address, port, username, password) from your account dashboard.
3.Open Tachiyomi → “Settings” → “Advanced” → “Proxy Settings.”
4.Toggle “Enable Proxy” → Enter your IPFLY details (select HTTP/HTTPS/SOCKS5—all supported by IPFLY).
5.Save settings → Restart Tachiyomi.
IPFLY’s residential proxies are undetectable by Cloudflare, so the “bypass failed” error disappears instantly. For manga fans who batch-download or read daily, this is a permanent fix.
Customize Your User-Agent
Make Tachiyomi look like a real browser to Cloudflare:
Go to Tachiyomi “Settings” → “Advanced” → “User-Agent.”
Replace the default string with a real browser’s user-agent (e.g., Chrome’s latest user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36).
Save → Restart Tachiyomi.
You can find up-to-date user-agents by searching “latest Chrome user-agent” online—update it every 3-6 months.
Limit Request Speed (Avoid Triggering Cloudflare)
Cloudflare blocks “bot-like” rapid requests. Slow down Tachiyomi’s activity:
Disable batch-downloading (download 5-10 chapters at a time instead of 50).
Enable “Delay Between Requests” in Tachiyomi’s settings: Go to “Settings” → “Advanced” → “Network” → Set delay to 1-2 seconds.
Switch sources if one is giving repeated errors (e.g., if “MangaDex” fails, try “MangaPark”—different sources have different Cloudflare strictness).
Clear Tachiyomi’s Cache & Cookies
Corrupted cache or cookies can interfere with bypass tools. Here’s how to clear them:
Go to Tachiyomi “Settings” → “Advanced” → “Clear Cache” and “Clear Cookies.”
Restart Tachiyomi → Try accessing the manga source again.
How IPFLY Makes Tachiyomi’s Cloudflare Bypass Foolproof
While the steps above fix the error, IPFLY ensures it never comes back. Here’s why manga fans swear by IPFLY for Tachiyomi:
Undetectable by Cloudflare
IPFLY’s residential proxies are tied to real devices, so Cloudflare can’t distinguish them from a human browsing Chrome. Even Cloudflare’s strictest “I’m Under Attack Mode” won’t flag you.
Global Manga Access
Many manga sources are geo-restricted (e.g., Korean manga only available in Korea). IPFLY’s 190+ country coverage lets you switch to a local IP—bypassing both Cloudflare and geo-blocks.
Stable & Fast for Manga
Free proxies lag or disconnect mid-chapter. IPFLY’s 99.9% uptime and low latency ensure smooth reading and downloading—no buffering while Cloudflare verifies you’re human.
Works with All Tachiyomi Extensions

Keep JS Enabled
Never disable JavaScript—even if a source loads slower, it’s worth it to pass Cloudflare’s challenge.
Myths About Tachiyomi Cloudflare Bypass (Busted!)
Let’s correct common misinformation that’s making your bypass fail:
“Free Proxies Work Just as Well”
False. Free proxies are shared and blacklisted—they’ll fail within hours. IPFLY’s residential proxies are the only reliable option.
“Disabling JS Speeds Up Bypass”
False. Disabling JS directly fails Cloudflare’s challenge—you’ll never bypass it.
“Tachiyomi’s Built-In Bypass Is Enough”
Partially true, but outdated. Tachiyomi’s built-in bypass works for basic Cloudflare checks, but pairing it with IPFLY defeats advanced security measures.
“Batch-Downloading Doesn’t Matter”
False. Cloudflare detects rapid requests as bot activity—batch-downloading 50 chapters triggers an instant block.
Enjoy Uninterrupted Manga with Tachiyomi & IPFLY
Failing to bypass Cloudflare with Tachiyomi is frustrating, but it’s fixable—most users just need to update their app, enable JS, and use a reliable proxy like IPFLY.
The key takeaway: Cloudflare’s security is getting stricter, but Tachiyomi can keep up—if you use the right tools. IPFLY’s residential proxies mimic human traffic, pass Cloudflare’s checks, and unlock global manga sources—all while keeping your reading smooth and uninterrupted.
