What Is ERR_SSL_PROTOCOL_ERROR?
When Chrome shows ERR_SSL_PROTOCOL_ERROR, it means the SSL / TLS handshake, the secret process that creates a secure, encrypted connection, failed due to a protocol mismatch or certificate problem.
In plain English: your browser and the website can’t agree on how to speak securely. So, Chrome stops the connection and warns you.
Why Does This Error Occur?
Several reasons can cause this issue, including:
- Outdated Browser: Using an old browser version may cause problems with newer security standards.
- Wrong System Date & Time: SSL certificates rely on the correct date and time settings.
- Cached Data Conflicts: Stored cookies or cached files might interfere.
- Firewall or Antivirus Settings: Sometimes security software blocks secure connections.
- Website’s SSL Certificate Problems: The website might have expired or misconfigured certificates.
- Network Issues: Public Wi-Fi or proxy settings can also cause SSL errors.
How to Fix It: Step-by-Step Guide
1. Check Your Date and Time Settings
Make sure your computer’s clock matches the actual time. An incorrect date or time can make SSL certificates appear invalid.
- On Windows: Right-click the clock → Adjust date/time → Turn on Set time automatically.
- On Mac: System Preferences → Date & Time → Set date and time automatically.
2. Clear Your Browser Cache and Cookies
Old or corrupted data can cause problems. Clearing your cache helps your browser get fresh files from the website.
- On Chrome: Go to Settings > Privacy > Clear Browsing Data.
3. Update Your Browser
Always keep your browser up to date. New versions support the latest security features and protocols.
4. Disable Firewall or Antivirus Temporarily
Sometimes security apps block SSL connections. Try turning them off briefly to see if that fixes the issue. Just remember to turn them back on afterward!
5. Try a Different Network
Switching from Wi-Fi to mobile data or another network can help if your current connection is causing the problem.
6. Disable Problematic Extensions
Some add-ons might interfere with secure connections. Disable your extensions one by one to identify the culprit.
Chrome menu → More tools → Extensions → Toggle off any new or suspicious plugins.
Quick Fixes for ERR_SSL_PROTOCOL_ERROR in Specific Scenarios
1. Fix ERR_SSL_PROTOCOL_ERROR on Android
- Go to Settings > Apps > Your browser and clear cache and data.
- Check your device’s date and time to make sure it’s accurate.
- Update your Android system and browser app to the latest versions.
- If using a VPN, disable it temporarily and try again.
2. Fixing ERR_SSL_PROTOCOL_ERROR on Localhost

- Clear your browser cache before testing local sites.
- Try using HTTP instead of HTTPS if SSL is not configured locally.
- Restart your local development environment and browser.
3. ERR_SSL_PROTOCOL_ERROR on All Browsers
- Clear SSL state from your system:
- In Chrome, go to Settings > Privacy and Security > Clear browsing data > Advanced > Select Cached images and files, Cookies and other site data, and Hosted app data, then clear.
- In Chrome, go to Settings > Privacy and Security > Clear browsing data > Advanced > Select Cached images and files, Cookies and other site data, and Hosted app data, then clear.

- Reset your network settings or flush DNS cache (via command prompt/terminal).
- Temporarily disable antivirus/firewall and test again.
