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 like cafes or airports need you to sign in. To see 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: Open the page in Incognito mode (computer only)

Open the page you were visiting in an Incognito window.

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

Step 3: Update your operating system

Make sure 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're done.

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.
