Unable to login to Zoh Mail admin console directly

Unable to login to Zoh Mail admin console directly

Hi,

Whenever I visit mailadmin.zoho.com, the page redirects to  https://www.zoho.com/mail/.

Means, I am not able to login to my Zoho mail admin console directly. I have to firstly login to Zoho mail and then navigate to control panel.
It is hectic for me, I had tried this in many systems, but the same problem every in every pcs.
