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.
"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.
"ERR_CERT_SYMANTEC_LEGACY"
"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://."
- 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: 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.

"Your clock is behind," "Your clock is ahead," or "NET::ERR_CERT_DATE_INVALID"

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.

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.
