If you just bought your new server powered with cPanel/WHM and you went to login at WHM/cPanel using secure connection (https://) and got that red error saying that certificate can not be trusted.
You can just press “Proceed Anyway” and get to WHH, cPanel or Webmail login but that will just bypass it but it becomes quite annoying.
Well there are two actually. First one includes buying SSL Certificate and those come at price from about $10 to few hundred bucks per year. If you sell hosting – I would recommend buying and installing one – but if you’re using the server alone – you can do it this way:
1. Login to cPanel/WHM (you’re clicking “Proceed Anyway” button for the last time I promise 🙂 )
2. Go to SSL/TLS and select SSL Key/Crt Manager in the menu
7. This is important step for all Windows Vista, Windows 7 and Windows 8 users. Select Place all certificates in following store then click Browse and in new small windows select Trusted Root Certificate Authorities, press OK and Next >
9. Restart the browser
10. Navigate to WHM, cPanel or Webmail secure login and you should no longer have that red error warning!
As I’ve said if you’re in hosting business – don’t be cheap buy a real SSL and install it. If you share server with a friend(s) or a business partner(s) just zip that whmcert.crt and email it to them and email them this article as a guide how to install the certificate. They have to do it from point 5. to point 10. Hope this helps!
