  • The ERR_CERT_SYMANTEC_LEGACY  error in Chrome is related to old Symantec certificates that Chrome no longer supports.
  • There are indeed a few Chrome settings to check and see if the issue is solved.
  • If it isn't, an alternative browser should be a solution.
  • Unfortunately, Firefox doesn't support the Symantec certificates either.

Instead of fixing issues with Chrome, you can try a better browser: OperaYou deserve a better browser ! 350 million people use Opera daily, a fully-fledged navigation experience that comes with various built-in packages, enhanced resource consumption and great design. Here's what Opera can do:

  • Easy migration: use the Opera assistant to transfer exiting data, such as bookmarks, passwords, etc.
  • Optimize resource usage: your RAM memory is used more efficiently than Chrome does
  • Enhanced privacy: free and unlimited VPN integrated
  • No ads: built-in Ad Blocker speeds up loading of pages and protects against data-mining
  • Download Opera

The ERR_CERT_SYMANTEC_LEGACY error can arise when users try to open website pages in Google Chrome.

In many cases, that issue is due to users trying to open webpages with Symantec certificates that more recent Chrome versions no longer support.

However, it can also be due to a few other factors that some users might be able to fix with the resolutions below.

How can I fix the NET::ERR_CERT_SYMANTEC_LEGACY error?

1. Open the page in another browser

switch to opera browser

As mentioned, if the page error arises due to antiquated Symantec certificates that Chrome (and Firefox) no longer supports, there isn’t that much you can do to solve the issue.

However, the same page will probably still work just fine in Opera so, try opening the webpage in this browser.

Opera is a great browser when it comes to fast browsing, online security, and customization features.

Your device will be at all-time protected from malware and annoying ads with the free VPN and built-in adblocker.

The way you can manage the opened tabs is pretty amazing as well. The workspace features, Search in tabs, and integrated Facebook and Instagram messenger allows you to optimize your work and keep everything only one click away.



If you want a reliable browser, fast connection with a flexible and easy to customize interface then this is your best choice!

The ERR_CERT_SYMANTEC_LEGACY error might sometimes be caused by third-party antivirus utilities.

Try temporarily turning off third-party antivirus software. You can usually do that by right-clicking the antivirus utility’s system tray icon and selecting a disable option.

Thereafter, try opening the same website page in Chrome with the antivirus utility disabled.

5. Contact the website’s webmaster

If you can open the same webpage ok in an alternative browser, get in touch with the website’s webmaster.

The website might include a contact link somewhere with which you can send an email to the webmaster.

Tell the webmaster that you can’t open his website’s pages with Google Chrome due to an ERR_CERT_SYMANTEC_LEGACY error.

Then the webmaster will probably realize that he needs to replace the certificate on the site with a new one to fix the issue.

Those are a few potential fixes for when you can’t open web pages in Google Chrome.
