Redirect errors

"This webpage has a redirect loop" or "ERR_TOO_MANY_REDIRECTS"

You'll get 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 to delete your cookies.

Secure connection errors

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

You'll get this error if the page has 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.

Certificate, connection not private, or invalid errors

"ERR_CERT_SYMANTEC_LEGACY"

If the error mentions Symantec, ask the site owner to update the site's certificate. Learn 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

You need to sign in to Wi-Fi networks at places like cafes or airports. To check the sign-in page, visit a page that uses "http://."

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

Step 2: For computers, open the page in Incognito mode

Open the page you want to visit in an Incognito window.

If the page opens and a Chrome extension doesn't work right, turn off the extension. Learn how to turn off Chrome extensions.

Step 3: Update your operating system

Make sure that your device, like Windows or Mac, is up-to-date.

Step 4: Temporarily turn off your antivirus

You'll get this error if you have antivirus software that provides "HTTPS protection" or "HTTPS scanning." The antivirus prevents Chrome from providing security.

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

Remember to turn your antivirus software back on when you're done.

Step 5: Get extra help

If you’re on a work computer with a proxy configuration, going through a proxy that does HTTPS interception, such as ZScaler, Palo Alto, or Fortinet, and you get “NET::ERR_CERT_AUTHORITY_INVALID” error, it likely means the required certificate from the proxy server isn’t installed. You should contact your administrator. We don't recommend that you install a certificate on your own, as that’s usually a security risk.

If you still get 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 use a Wi-Fi portal where you have to sign in before you can get online.

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

"Your clock is behind," "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 the time and date are correct.

"Delete Expired DigiCert Certificate"

Important: This is for Mac computers only.

You'll get this error if the page uses a certificate that isn't set up right on your computer.

To fix the error:

  1. On your computer, at the top right, select Spotlight search Search.
  2. Enter Keychain Access.
  3. In the results, select Keychain Access.
  4. Select Open Keychain Access (if applicable).
  5. At the top of your computer screen, select View and then Show Expired Certificates.
  6. At the top right of the "Keychain Access" window, select Search Search.
  7. Find "DigiCert High Assurance EV Root CA" that's marked as Expired Expired.
  8. Select the certificate.
  9. On your keyboard, press Delete.
Weak security errors

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

You'll get this error if you try to go to a website with an outdated security code. You can’t connect to these sites because Chrome protects your privacy.

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 webpage is not available" or "ERR_SSL_VERSION_OR_CIPHER_MISMATCH"

You'll get this error if you try to go to a website with an outdated security code. You can’t connect to these sites because Chrome protects your privacy.

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. Avoid RC4 since it’s no longer considered secure. If you can't turn off RC4, make sure that other non-RC4 ciphers are turned on.

"Software on your computer is stopping Chrome from safely connecting to the web"

Important: This is for Windows computers only.

You'll get this error if you have Superfish software on your Windows computer. To remove this software from your computer:

  1. On your computer, open Chrome.
  2. Go to Lenovo's support page for this problem.
  3. Select Download SuperFish Removal Tool.
  4. At the top right, select the filename Lenovo.SuperFishRemovalTool.exe.
  5. Follow the on-screen instructions.

"Did you mean [site name]?"

You’ll get this message if the link you opened goes to a site with a slightly different name from one you usually visit. You’ll be asked by Chrome if you want to go to the site you usually visit.

  • To go to the site Chrome suggests, select the name of the site or Continue.
  • To continue to the link you opened, select Ignore.
