How to fix a certificate error navigation blocked

There are several things you can do to get around the Certificate Error Navigation Block issue and reach the site you want to access.

Avoid navigating past warnings such as the Certificate Error Navigation Blocked warning. Sites that have security certificates are secure to browse, and don’t contain malware that could harm a system. These errors can be dangerous for your computer and privacy.

  1. You can verify that the error was not unjustified. You may be able to access additional information about the site’s SSL certificate depending on the source of the error. You can also access this information using most browsers by clicking the lock in the address bar. If the expiration date of the certificate is older than the current date, it is expired and you have nothing to do.
  2. Run a Windows Update. Sometimes an obsolete piece of software is the problem.
  3. Use a different browser. Google Chrome, Firefox handle things differently to Edge. It is possible that one site may not work on the other.
  4. You can update the problem browser. Edge and IE can be updated with Windows Update, but updating Chrome or Firefox is also possible.
  5. Set the Windows operating system clock. Windows will not use the correct time to determine the expiration date of the certificate if the clock is wrong.
  6. DNS servers should direct the connection to the correct website. These DNS servers must be updated if a website makes major changes, such as the address of its hosting location. All DNS servers are not updated at the same speed or contain the same information. Check your DNS servers and see if they are correct.
  7. Make sure your firewall and antivirus settings are correct. Check that the firewall and antivirus program aren’t blocking access to the site. Sometimes, an antivirus program blocks access to key areas of the site. A computer cannot do more than raise an error if it doesn’t have the right information. To resolve the problem, you can loosen the firewall or antivirus restrictions.
    Another option, though risky, is to temporarily disable McAfee or Norton or the Windows firewall. This option can put your computer at risk of being hacked. After you are done, restart the firewall or antivirus.
  8. Remove Trusteer Rapport. Trusteer Rapport is a piece of IBM software that provides extra protection for online information. Trusteer Rapport can lead to errors and bugs. Trusteer Rapport can be removed while your antivirus remains fully functional.
  9. Modify the internet security settings. To see if this solves the problem, lower the security level in Windows.
  10. Disable protected mode in Internet Explorer. Disable protected mode if the problem is only in Internet Explorer.
    Protected mode exists for a reason. You should disable it only if the error is not being corrected and there’s no legitimate reason to block the site.
  11. Internet Explorer can be trusted to add trusted sites. Permanently add the site to Internet Explorer and Microsoft Edge if you are certain that the error is not caused. Enter Windows key+R and then select OK.
  12. Disable certificate mismatch warnings. This will prevent the error from appearing. This temporary solution doesn’t address the root problem.
    1. Open the Internet Properties Window.
    2. Select the Advanced tab.
    3. Take a look at the table for Warning about certificate address mismatch and then remove the checkbox to disable it.
    4. To apply the change, press Ok
    5. Start the browser again to access the site.
