Get help with a specific error message

'This web page has a redirect loop' or 'ERR_TOO_MANY_REDIRECTS'

You'll see this error when the page has tried to redirect you too many times.

Sometimes, pages don't open because cookies aren't working correctly. To fix the error, try deleting your cookies.

'This site can't provide a secure connection; network-error sent an invalid response' or 'ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION'

You'll see this error if the page had an error that Chrome couldn't understand. To fix the error, contact the website owner.

If you own this website, learn how to fix the ERR_SSL_FALLBACK_BEYOND_MINIMUM_VERSION error.

'ERR_CERT_SYMANTEC_LEGACY'

If the error mentions Symantec, ask the site owner to update the site's certificate. Learn more about why Symantec issued certificates aren't supported.

'Your connection is not private', NET::ERR_CERT_AUTHORITY_INVALID', 'ERR_CERT_COMMON_NAME_INVALID', 'NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM', 'ERR_CERTIFICATE_TRANSPARENCY_REQUIRED' or 'SSL certificate error'

If the error mentions HSTS, privacy certificates or invalid names, try the following steps:

Step 1: Sign in to the portal

Wi-Fi networks at places such as cafés or airports need you to sign in. To see the sign-in page, visit a page that uses http://.

Go to any website starting with http://, like http://example.com.
On the sign-in page that opens, sign in to use the Internet.

Step 2: Open the page in Incognito mode (computer only)

Open the page that you were visiting in an Incognito window.

If the page opens, a Chrome extension isn't working correctly. To fix the error, turn off the extension. Learn how to turn off Chrome extensions.

Step 3: Update your operating system

Make sure that your device is up to date on Windows, Mac or another operating system.

Step 4: Temporarily turn off your antivirus

You'll see this error if you have antivirus software that provides 'HTTPS protection' or 'HTTPS scanning'. The antivirus is preventing Chrome from providing security.

To fix the problem, turn off your antivirus software. If the page works after turning off the software, turn off this software when you use secure sites.

Remember to turn your antivirus program back on when you've finished.

Step 5: Get extra help

If you still see the error, contact the website owner. You can also get more help on the Chrome Help forum.

'Connect to network'

You'll get this error if you're using a Wi-Fi portal where you have to sign in before you can get online.

To fix the error, click Connect on the page that you try to open.

'Your clock is behind' or 'Your clock is ahead' or 'NET::ERR_CERT_DATE_INVALID'

You'll get this error if your computer or mobile device's date and time are inaccurate.

To fix the error, open your device's clock. Make sure that the time and date are correct.

'Server has a weak ephemeral Diffie-Hellman public key' or 'ERR_SSL_WEAK_EPHEMERAL_DH_KEY'

You'll see this error if you try to go to a website with an outdated security code. Chrome protects your privacy by not letting you connect to these sites.

If you own this website, try to update your server to support ECDHE and turn off DHE. If ECDHE is unavailable, you can turn off all DHE cipher suites and use plain RSA.

'This web page is not available' or 'ERR_SSL_VERSION_OR_CIPHER_MISMATCH'

You'll see this error if you try to go to a website with an outdated security code. Chrome protects your privacy by not letting you connect to these sites.

If you own this website, try to set your server to use TLS 1.2 and TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, instead of RC4. RC4 is no longer considered secure. If you can't turn off RC4, make sure that other non-RC4 ciphers are turned on.

Click Download Superfish Removal Tool.
At the bottom, click the filename (Lenovo.SuperFishRemovalTool.exe).
Follow the onscreen instructions.

'Delete Expired DigiCert Certificate' (Mac computers only)

Did you mean [site name]?

You’ll see this message if the link that you opened goes to a site with a slightly different name from one that you usually visit. Chrome will ask if you want to go to the site that you usually visit.

Click Ignore to continue to the link that you opened.
