How to remove WHM/CPanel untrusted certificate error

Untrusted certificate
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.
WHM cPanel certificate not trusted - The security certificate presented by this website was not issued by a trusted certificate authority. Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server

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.

The Solution
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

3. In the Certificates find the your host and download click the download button/icon:
SSL Key Crt Manager

4. Copy everything from (including) —–BEGIN CERTIFICATE—– to (including) —–END CERTIFICATE—– and paste it in a notepad and save that as whmcert.crt on desktop.
SSL Certificate

5. Double click on that file you have just saved/created and click on Install Certificate button.

6. Just click Next > 🙂
SSL install step 2

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 >
SSL install step 3

8. Press Finish
SSL install step 4

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!
