Hello Brian.Mattucci,
Thank you for your question. I tested your cpanel and I am able to login successfully. You may be experiencing connectivity/routing issues, or on a network that is blocking certain ports. It is common for networks to block secure ports.
There are multiple ways to access your cpanel, I reccomend trying some of the alternate links to determine where the issue is.
These all go to your cPanel (be sure to replace domain.com with your actual domain) :
cpanel.domain.com
domain.com/cPanel
Also:
https://secure122.inmotionhosting.com:2083https://cpanel.secure122.inmotionhosting.com
If none of these are working or this occurs again, I recommend performing a Ping/Tracert in order to determine where the connections stops.
If you have any further questions, feel free to post them below.
Thank you,
-John-Paul
