Unable to establish a secure connection because root certificate is missing

Asked By 10 points N/A Posted on -


Some errors to connect to this website, and is not the only one who give me error. I have checked the certificates of my browser and none is missing. I have this error with two different browsers and I can’t solve it. Anyone have any idea how to solve these errors? Is there a way to update the certificates or add new ones?

Thank you !

You first need to save the certificate to your desktop. Once it is downloaded double-click it to display the Add Certificates window and launches the Keychain Access application. See image.

Click the popup menu next to Keychain and select X509Anchors. Click OK. See image.

When it prompts you for a password, enter the administrator password and click OK. See image.

And that’s it. The root certificate is now installed. Now to verify if your certificate is installed properly, go to Applications, Microsoft Office 2004, Office, and select Microsoft Cert Manager. Select Apple Trusted Root Certificate Authorities then find the certificate you just installed. Double-click the certificate and you should get something like this. See image.
