When you access WHM, Cpanel or webmail via cp1.skywebbox.com then our server redirects to "https" protocol
By default the SSL certificate is configured on our server would be a self-signed one, essentially meaning that it has not been issued by a CA, but instead your own server has signed the certificate as being valid.
For bypassing the SSL warning in popular web-browsers in the time of browsing, use the following methods
Google Chrome:
Click on Advanced, then Proceed to your-domain-name.com (unsafe) to bypass SSL warning in Chrome.
Mozilla FireFox:
Click on I Understand the Risks, then click on Add Exception.
Next click on Get Certificate, and finally Confirm Security Exception to bypass SSL warning in FireFox.
Microsoft Internet Explorer:
Click on Continue to this website (not recommended) to bypass SSL warning in Internet Explorer.
This warning is simply letting you know that the SSL certificate was self-signed. In the case of accessing your own server this isn't a problem at all, and you can simply tell your web-browser to accept the self-signed SSL certificate and continue.
