Server Management Company Or Me

I initially posted a topic to get help with a problem because I want to fix it myself without wasting the time of the server management company. They however picked up the post and said I should opened a ticket with them.

The problem is however still not resolved to my satifaction after a few days because we differ on some points so can you please air your view on this matter?

-----------------

[url]or [url]

Problem 1) Certificate error that hostname and certificate name don't match.

Problem 2) At some places in WHM or cPanel there is a secure and non secure warning items.

The problem 2 is perhaps to bug in WHM V11 so it is not so important.

However, the server mangement staff insist that problem 1 is because the login is via IP (or other domain name) and not via hostname but I don't agree with them because.

a) During the years I always logged into whm or cpanel via ip or domain names and never got such error.

b) cPanel redirect any whm or cpanel access to the ssl ports under HOSTNAME so it MUST match the certificate even if you use 75.127.69.82:2087

I don't get any error if log in with [url]so it is clear that the redirection to ssl ports under HOSTNAME like above don't work correctly.

That the redirection works can be seen by using [url]because the same error comes up (for mercury.domain.com) despite the site have his own certificate.

What we have here is.

Hostname = mercury.domain.com
Certificate Name = mercury.domain.com

[url] (Works Fine because certificate name is mercury.domain.com)

[url] (Name of site don't match mercury.domain.com despite redirection to hostname IN WHM)

[url](Works fine, Host name = othersite.com and match certificate name)

[url](Name of site don't match mercury.domain.com despite redirection to hostname IN WHM)

What I suspect is that cpanel redirect but NOT to the actual hostname (mercury.domain.com) or otherwise present/display the hostname incorrectly so that it don't match the certificate.

WHM 11 setting: Redirect to ssl ports = enabled
Two further settings, redirect to hostname = enabled

(None of the settings have any effect anyway and I tested hostname, certificate name and origin domain name redirect with the same results)
