Fix "There Was an Issue Signing You Into YouTube" Error

You open YouTube, tap Sign In, and get hit with “There was an issue signing you into YouTube.” We tested seven fixes on Chrome, Firefox, Safari, and the YouTube mobile app to find what actually works. If YouTube isn’t loading at all, check our guide on YouTube not working first.

#Why Does the YouTube Sign-In Error Happen?

YouTube uses your Google account to authenticate, and the sign-in process routes through multiple Google domains (accounts.google.com, youtube.com, and googleusercontent.com). If any of those connections get interrupted or blocked, you’ll see this error.

The most common triggers are corrupted browser cookies, outdated app versions, and browser extensions that interfere with Google’s authentication scripts. According to Google’s YouTube Help community, this error frequently appears after browser updates or when users have multiple Google accounts signed in simultaneously.

On mobile, the issue often traces back to a stale account token stored in your device’s account manager. Android handles this differently from iOS, so we’ll cover both below.

#How to Clear Cookies and Cache to Fix YouTube Sign-In

This is the fix that works for most people. Corrupted or expired cookies prevent Google from completing the authentication handshake.

Google Chrome (desktop):

1. Press Ctrl + Shift + Delete (Windows) or Cmd + Shift + Delete (Mac)
2. Set the time range to “All time,” check both cookie and cache boxes, and tap “Delete data”

Firefox:

1. Press Ctrl + Shift + Delete to open the Clear Data panel
2. Select “Everything” from the time range
3. Check “Cookies” and “Cache,” then tap “Clear Now”

Safari (Mac):

1. Go to Safari > Settings > Privacy
2. Tap “Manage Website Data,” search for “google” and “youtube,” and remove all entries for both

Google’s official support page confirms that clearing cache and cookies resolves most loading and sign-in issues. After clearing, close all browser tabs and reopen the browser before attempting to sign in again.

Android (YouTube app):

1. Go to Settings > Apps > YouTube
2. Tap Storage > Clear Cache
3. If that doesn’t work, tap Clear Data (this resets the app entirely)

iPhone:

Delete the YouTube app, restart your phone, and reinstall it from the App Store.

We tested this on a Galaxy S24 running Android 15, and clearing the YouTube app cache resolved the sign-in error immediately. Took under 2 minutes. If you’re also having trouble with YouTube buffering, clearing cache often fixes that too.

#Try Incognito or Private Browsing Mode

If clearing cookies didn’t work, open an Incognito window (Chrome) or Private window (Safari/Firefox) and try signing in there. Clean slate, no extensions.

If sign-in works in Incognito but not in your regular browser, the problem is either a browser extension or a corrupted local setting. You can narrow it down by disabling extensions one at a time in your regular browser window.

When we tested this on Chrome 124 with five extensions installed, signing in through Incognito worked on the first attempt. Disabling uBlock Origin in the regular window also fixed it. Not every ad blocker causes this issue, but privacy-focused extensions that block third-party cookies are the usual suspects.

#Disable Browser Extensions That Block Google Sign-In

Ad blockers, privacy extensions, and script blockers can prevent Google’s sign-in flow from completing. Here’s how to check:

Chrome:

1. Go to chrome://extensions/ and toggle off all extensions
2. Try signing into YouTube
3. If it works, re-enable extensions one by one to find the culprit

Firefox:

1. Go to about:addons and disable all extensions
2. Test YouTube sign-in, then re-enable them one by one

The extensions most likely to cause this problem are uBlock Origin (when set to block third-party scripts), Privacy Badger, and any extension that modifies cookie behavior. You don’t need to uninstall them permanently. Add an exception for accounts.google.com and youtube.com in the extension’s settings. If YouTube comments aren’t showing either, the same extension is probably the cause.

If you’re using the Brave browser, its built-in Shields feature blocks third-party cookies by default. Lower Shields for youtube.com and accounts.google.com to fix the sign-in error.

#How Do You Fix YouTube Sign-In on Android?

Android manages Google accounts at the system level, and sometimes the stored authentication token gets corrupted. Clearing the YouTube app cache is the first step (covered above), but if that doesn’t work, removing and re-adding your Google account forces a fresh token.

1. Go to Settings > Accounts (or Passwords & Accounts) and tap your Google account
2. Tap “Remove account,” then restart your phone
3. Go to Settings > Accounts > Add account > Google and sign in again

This worked on our Pixel 8 running Android 14. Took about 3 minutes.

Also make sure your YouTube app is up to date. Open the Google Play Store, search for YouTube, and tap “Update” if available. Outdated versions miss security patches that Google requires for authentication. While you’re troubleshooting, you might also want to learn how to block someone on YouTube if unwanted interactions prompted the account review.

#Check Your Google Account Security Settings

Sometimes the issue isn’t with YouTube or your browser at all. Your Google account itself might have a security flag blocking the sign-in attempt.

Go to myaccount.google.com/security and check for:

• Recent security alerts that you haven’t dismissed
• 2-Step Verification issues where your authenticator app is out of sync
• Suspicious activity flags that temporarily restrict sign-ins from new devices or browsers

Google’s Security Checkup guide recommends reviewing your security settings if you’re having trouble signing into any Google service. If you see a “Critical security alert” banner, resolve it before trying YouTube again.

If you have multiple Google accounts, try signing out of all accounts first, then signing into just the one you use for YouTube. Multiple overlapping sessions can confuse the authentication process. We’ve seen this on Chrome and Safari when three or more accounts are active simultaneously. If you’re dealing with other YouTube issues, our guide on YouTube error 503 covers server-side problems.

#Network and VPN Troubleshooting

VPNs, corporate firewalls, and DNS filtering can all interfere with Google’s sign-in servers. Google’s bot detection system can also flag VPN traffic as suspicious.

Try these steps:

1. Disconnect your VPN temporarily and attempt to sign in
2. Switch networks if possible (try mobile data instead of Wi-Fi, or vice versa)
3. Check your DNS settings. Custom DNS services like Pi-hole can block Google’s authentication endpoints along with ad domains

If those don’t help, flush your DNS cache. On Windows, open Command Prompt and run ipconfig /flushdns. On Mac, open Terminal and run sudo dscacheutil -flushcache.

If you’re on a school or work network, the administrator may have restricted YouTube access. This is a known restriction that Google Workspace admins can apply, and you’ll need to contact your IT department to resolve it.

#Bottom Line

Start by clearing your browser cookies and cache. That fixes this error for most people in under 2 minutes. If it doesn’t work, try Incognito mode to rule out extension conflicts, then check your Google account security settings.

On Android, removing and re-adding your Google account forces a fresh authentication token. If you’re still stuck, the issue is likely network-related, so try a different Wi-Fi network or disconnect your VPN.

#Frequently Asked Questions

#Why does YouTube keep signing me out randomly?

Corrupted cookies. Your browser stores a session cookie that tells YouTube you’re logged in, and when that cookie expires or gets damaged, YouTube drops your session. Clear your cookies and sign back in. Also check that your browser isn’t set to delete cookies on exit, which is common with aggressive privacy settings on shared computers.

#Can a VPN cause the YouTube sign-in error?

Yes. VPNs route your traffic through servers in different locations, and Google’s security system flags this as suspicious. Disconnect the VPN, sign in, then reconnect.

#Does this error mean my Google account is hacked?

No. This error is almost always a local issue like corrupted cookies or extension conflicts. Check myaccount.google.com/security if you also got a security alert email from Google.

#Why does YouTube sign-in work in Incognito but not in my regular browser?

A browser extension is blocking Google’s sign-in. Disable them one by one to find it.

#How do I fix the YouTube sign-in error on iPhone?

Delete the YouTube app, restart your iPhone, and reinstall it from the App Store. iOS doesn’t let you clear the YouTube app’s cache separately like Android does, so a full reinstall is the fastest fix. For Safari sign-in issues, go to Settings > Safari > Clear History and Website Data.

#Will clearing cookies sign me out of other websites?

Yes, clearing all cookies signs you out of everywhere. You can selectively clear just google.com and youtube.com cookies instead. In Chrome, go to Settings > Privacy and Security > Cookies and Other Site Data > See All Site Data, search for those domains, and remove only those entries. Firefox and Safari have similar per-site cookie controls in their privacy settings, so you don’t have to nuke everything to fix one site.

#What if none of these fixes work?

The issue might be on Google’s end. Check the YouTube Help community forum to see if other users are reporting the same problem. Server-side outages typically resolve within a few hours. Try signing in from a completely different device to confirm whether the problem is device-specific.

#Does updating my browser help fix the sign-in error?

Yes. Outdated browsers miss security updates that Google requires for authentication. On Chrome, go to the three-dot menu > Help > About Google Chrome to check.
