Resolve “Login Failed,” “No internet connection,” and sign-in loops with official developer fixes and community-verified solutions for Android 2026.
YouTube Vanced was discontinued in March 2022. If you are using a legacy Vanced install, migrate to ReVanced — the actively maintained successor. This guide covers ReVanced login troubleshooting for Android 2026.
ReVanced is the open-source successor to YouTube Vanced, offering ad-blocking, background playback, SponsorBlock, and Return YouTube Dislike by patching the official YouTube app. However, login errors — especially “Login Failed,” “No internet connection,” and sign-in loops — are the most reported issues in the ReVanced community.
This guide compiles official ReVanced developer fixes, community-verified solutions from the ReVanced community, and device-specific troubleshooting to resolve sign-in failures fast.
How ReVanced Sign-In Works
ReVanced does not ship as a pre-built APK. Instead, you use ReVanced Manager to patch an official YouTube APK. For Google sign-in on non-root devices, the "GmsCore support" patch is mandatory. This patch redirects authentication to ReVanced GmsCore — an actively maintained fork of MicroG — instead of standard Google Play Services.
Patch Official YouTube
You control the version and patches applied to the official YouTube APK.
ReVanced GmsCore
Replaces discontinued Vanced MicroG with actively maintained authentication.
Latest Support
Latest supported YouTube version: 20.14.43 (as of February 2026)
Released in March 2026 with improved patching stability and auto-selection of recommended patches.
Common Causes of ReVanced Login Errors

|---|---|---|

| Split APK used | ReVanced Manager requires a full (non-split) APK | Common |
| Corrupted auth tokens | Password changes or security alerts invalidate stored tokens | Common |
| Battery optimization | Android 15 aggressively kills GmsCore background processes | Very Common |
| “Device registration” enabled | Conflicts with Google’s updated auth on custom ROMs | Common |
| Outdated patches | YouTube updates break patch compatibility | Occasional |
| VPN/Proxy interference | Reroutes traffic away from Google auth endpoints | Occasional |
Quick Diagnosis: 60-Second Checklist
Before diving into fixes, run this checklist. Most users find the cause in under a minute.
If 5+ items are checked and login still fails, proceed to Step-by-Step Fixes below.
Step-by-Step Fixes
Update GmsCore (Resolves 80% of Login Loops)
In February 2026, ReVanced developers confirmed that Google introduced authentication changes that broke login in older GmsCore versions. The fix was merged upstream and released in ReVanced’s fork.
- Uninstall old GmsCore if you see “You are using a limited version of MicroG”
- Download the latest ReVanced GmsCore from the official the official source releases page
- Install the APK (allow unknown sources for your browser)
- Open GmsCore and grant all requested permissions
Do not use legacy com.mgoogle.android.gms (Vanced MicroG). ReVanced requires app.revanced.android.gms.
Repatch with “GmsCore Support” Included
If you patched YouTube without the GmsCore support patch, sign-in will fail permanently on non-root devices.
- Open ReVanced Manager → Patcher
- Select your YouTube APK (must be version 20.14.43, full non-split APK)
- Tap Select patches → Default/Recommended
- Verify “GmsCore support” is checked
- Patch and install
ReVanced Manager v2 auto-selects recommended patches for first-time users.
The “Remove Account from System Settings” Fix (Community-Verified)
This is the most upvoted fix on the ReVanced community for “No internet connection” errors.
- Go to Settings → Accounts → Manage accounts → Google
- Look for the blue “g” icon account (this is the GmsCore account, not your main Google account)
- Remove only the GmsCore-associated account
- Force-stop GmsCore
- Clear GmsCore cache and data
- Open ReVanced and sign in fresh
This removes stale authentication tokens without affecting your main Google account or other apps.
Disable “Authenticate with Device Registration”
If you see “There was a problem communicating with Google servers,” this fix is essential:
- Open GmsCore app
- Go to Settings → Google Accounts
- Find your account and disable “Authenticate with device registration”
- Also disable all sub-switches below the account if present
- Retry sign-in in ReVanced
This setting conflicts with Google’s updated authentication protocols, particularly on custom ROMs and after GmsCore updates.
Disable Battery Optimization (Android 15 Critical)
Android 15’s enhanced battery optimization is the leading cause of random sign-outs.
| Device | Path |
|---|---|
| Google Pixel | Settings → Apps → Special app access → Battery optimization → ReVanced & GmsCore → Don’t optimize |
| Samsung One UI 7 | Settings → Battery and device care → Battery → Background usage limits → Never sleeping apps → Add both |
| Xiaomi HyperOS | Settings → Battery → App battery saver → ReVanced & GmsCore → No restrictions |
| OnePlus OxygenOS 15 | Settings → Battery → Battery optimization → All apps → ReVanced & GmsCore → Don’t optimize |
Also enable: Settings → Apps → GmsCore → Mobile data & Wi-Fi → Allow background data.
Clear Cache and Data
- Settings → Apps → YouTube ReVanced → Storage → Clear cache → Clear storage
- Settings → Apps → GmsCore → Storage → Clear cache → Clear storage
- Restart device
- Sign in again
Full Reinstall (Nuclear Option)
If all fixes fail:
- Uninstall ReVanced and GmsCore
- Restart device
- Download latest ReVanced Manager from vanced.com.co
- Download latest GmsCore from the official source
- Download YouTube 20.14.43 full APK from vanced.com.co (ARM64, nodpi, not bundle)
- Patch with default patches including GmsCore support
- Install and sign in fresh
Device-Specific Fixes
Samsung Galaxy S24 / S25 (One UI 7)
Samsung’s One UI 7 introduced stricter background execution limits. In addition to battery optimization:
- Go to Settings → Apps → ReVanced → Battery → Unrestricted
- Go to Settings → Apps → GmsCore → Battery → Unrestricted
- Disable “Put unused apps to sleep” for both apps
- If using Secure Folder, ensure no duplicate ReVanced install exists there
Xiaomi / Redmi / POCO (HyperOS / MIUI)
Xiaomi devices are notorious for killing background apps:
- Settings → Battery → App battery saver → ReVanced & GmsCore → No restrictions
- Settings → Apps → Permissions → Other permissions → GmsCore → Allow all
- Security app → Battery → ReVanced & GmsCore → No restrictions
- Disable MIUI optimization in Developer Options if patches fail to apply
Google Pixel (Stock Android 15)
- Settings → Apps → Special app access → Battery optimization → All apps → ReVanced & GmsCore → Don’t optimize
- Enable “Allow unrestricted data” for GmsCore in Network & Internet settings
- If using a privacy-focused custom ROM, you must use the GmsCore support patch — sandboxed Google Play cannot replace GmsCore
Custom ROMs (custom ROMs, custom ROMs, custom ROMs)
- Ensure signature spoofing is supported if attempting to run without GmsCore
- Some ROMs require enabling microG support in Developer Options
- Use root tools for signature spoofing if needed

Conclusion
Most ReVanced login errors resolve by updating GmsCore, repatching with the GmsCore support patch, and removing stale accounts from system settings. Android 15’s stricter battery optimization makes the battery settings step critical in 2026.
