How to fix the SSL error ERR_CERT_COMMON_NAME_INVALID?

1. Empty Browser Cache

Please empty your browser cache, restart your browser and see if the problem still exists.

2. Start a private session

Sometimes a browser plugin might cause the error. If you open a new browser tab in a private session and the problem does not show up anymore it might be a plugin.

3. Clear SSL State in Browser

  • In Firefox press Ctrl-Shift-Delete to display the Clear All History dialog immediately. Select the Active Logins check box, before clicking on Clear Now.
  • In Internet Explorer click the Settings icon icon, and then click Internet options. Switch to the Content tab and click Clear SSL state, and then click OK.
  • In Google Chrome click the Settings icon and then click Settings. Then switch to Show advanced settings. Under Network, click Change proxy settings. The Internet Properties dialog box appears. Switch to the Content tab and click Clear SSL state, and then click OK.

4. Disable Antivirus or Firewall

Sometimes, your antivirus or firewall programs can mess with https sites. This is why your browser may show you some kinds of SSL error message. We recommend you to disable the security programs temporarily and check if that was the reason.
