The 400 error on Xiaomi devices is often due to firmware features MIUI, Cache conflicts or regional settings limitations.

In this article, we will discuss 7 proven ways to correct the error 400 Especially for Redmi smartphones (relevant for Note models) 10/11/12, Redmi 9/10/13C, POCO X3/X4/X5 Importantly, the methods range from the simplest to the most complex — start with the first point and move on only if the problem persists.

What is the 400 error in YouTube and why does it appear on Xiaomi?

The 400 Bad Request code is the standard code. HTTP-A server response that means that the request from your device is not generated correctly or contains inappropriate data. On Xiaomi Redmi smartphones, this error in YouTube occurs for several key reasons:

• 🔄 Application cache conflict: MIUI aggressively caches data, and over time YouTube files can get corrupted, especially after updates.
• 🌍 Regional restrictions: If the smartphone settings indicate a region other than the real one (for example, India instead of Russia), Google servers block some requests.
• 🛠️ Google Play Services Failures: On MIUI These services often run insecurely due to Xiaomi’s optimizations (especially on the Redmi budget models).
• 📡 Problems with DNS or IP-Address: If your provider uses "dirty» DNS (For example, from Rostelecom or MTS, YouTube may perceive requests as suspicious.

Fun fact: on the Mi Community forums, users note that the error 400 more often appears after the update MIUI shift SIM-This is because the system automatically changes the settings of the network, not optimizing them for work with YouTube.

Method 1: Clearing YouTube cache and data (works 65% of the time)

Let's start with the most efficient and safe method, and a damaged cache is the main cause of the 400 error on Xiaomi Redmi, because MIUI doesn't always manage temporary application files correctly.

1. Open Settings → Applications → Application Management.
2. Find YouTube on the list and tap it.
3. Go to Warehouse → Clear the cache (click twice if the button is inactive).
4. Go back and select Clear Data (this will delete your account history and settings, but not the videos themselves).
5. Reboot your smartphone.

If the error disappeared after cleaning, but returned after a few days, then the problem is deeper – most likely, Google services are to blame (see Method 4).

Method 2: Reset network settings (relevant to MIUI 13/14)

Incorrect mobile network or Wi-Fi settings can cause YouTube to perceive your queries as “fake,” which is especially true for the Xiaomi Redmi with two different types of mobile phone. SIM-maps MIUI Sometimes you get your connection priorities confused:

1. Go to Settings. → SIM-maps and mobile networks → Resetting network settings.
2. Confirm the action (password is not required).
3. After restarting manually select the network 4G/LTE customized SIM-Cards (automatic mode may fail).

If you use Wi-Fi, you can also:

• 📶 Forget the network in the settings and connect again.
• 🔒 Check what type of network security — WPA2-PSK (not WPA3, quiver MIUI).

💡

After resetting the network, disable the function of Intelligent Switching in the settings SIM-maps – it often causes a connection to break while watching videos.

Method 3: Change DNS to Google or Cloudflare

By default, Xiaomi Redmi uses your provider's DNS, which may be overloaded or blocked for some Google services.Switching to public DNS solves the problem 30% of the time.

1. Open Settings → Wi-Fi (or Mobile Network → Mobile Internet Access Point).
2. Tap on the current network → Change the network → Additional settings.
3. In the DNS field, type 8.8.8.8, 8.8.4.4 (or 1.1.1.1, 1.0.0.1 for Cloudflare).
4. Save and reconnect.

Method 4: Reinstall Google Play Services (for advanced ones)

On Xiaomi Redmi, Google services often run unstable due to MIUI optimizations. If previous methods did not work, you will have to manually update or reinstall these components. This method requires care - do not delete system files unless you are sure!

1. Download the latest version of Google Play Services (choose for your architecture: arm64 or armeabi).
2. Install. APK-File (Allow installation from unknown sources in Settings) → Annexes → Special rights).

1. Set it up solid. VPN-App (we recommend ProtonVPN or Windscribe – they do not slow down video).
2. Connect to a server in the Netherlands, Germany or the United States (don’t choose a nearby country like Turkey, there may be restrictions).
3. Open YouTube and check if the error has disappeared.

⚠️ Attention: Free of charge VPN (for example, Turbo VPN super VPN) They often sell your data and may make the problem worse.

VPN is a temporary solution. If error 400 only appears with the VPN, then the problem is in your main connection (see Method 3 about DNS).

Sometimes, the error 400 occurs after you update your YouTube app to the latest version, because new releases may contain bugs that are incompatible with MIUI.

3. Turn off auto-update for YouTube in Play Market (Menu) → My apps. → YouTube → ⋮ → Turn off auto-update).

If you don’t want to risk a rollback, try YouTube’s alternative clients:

• 🎥 NewPipe – open client without ads (no Google account required).
• 🌐 YouTube in the browser (Chrome/Firefox) desktop-requested (⋮ → PC version).

Method 7: Reset to factory settings (extreme case)

If none of these methods work, the last option is a hard reset, which will delete all the data from the phone, so first of all:

• 📱 Make a backup copy through Settings → Additionally. → Backup and reset.
• 🔐 Remember the username and password from the Mi Account (required to unlock after resetting).

2. Choose to erase all data and confirm.
3. After the reboot, set up your phone as new, but don’t restore your backup – check YouTube first.

⚠️ Note: Some Redmi models (e.g. Note 11 Pro)+) After the reset, you may need to re-assign your Mi Account through SMS. Make sure you have access to the phone number linked to your account.

How to avoid the 400 error in the future

To prevent error 400 from returning, follow these guidelines:

• 🔄 Regularly (once a month) clear the YouTube cache through Settings → Warehouse.
• 🚫 Don’t install “optimizers” or “memory cleaners” – they often break Google’s services.
• 📱 Update. MIUI Only through official channels (Settings) → Updating the system).
• 🌐 Use Firefox or Kiwi Browser to view YouTube – they are less likely to crash than the built-in Mi Browser.

If you often encounter bugs on YouTube, consider installing custom firmware (like Pixel Experience or LineageOS) that lacks MIUI optimizations that conflict with Google services. However, this requires unlocking the bootloader and experience — for beginners, the method is not suitable.

💡

The most reliable way to avoid the 400 error is to use YouTube through a browser with the PC mode enabled, in which case the request is not through the application, but directly, bypassing possible MIUI bugs.
