Group Manager web console and vCenter plugin take 20 minutes to load

​Lately for some reason the EqualLogic web console and the screen in the vSphere client for the vCenter plugin take literally 20 minutes to load. When i browse to and want to open the web console for group manager or the plugin page in the vSphere client i get the blue Dell logo in the upper left hand corner and it just sits there. After literally 20 minutes I will finally get the box to enter the login credentials and once logged in everything seems to work fine, until I log out and have to go through the 20 minute process again.​

​Has anyone encountered this problem before or know what might be causing it? Maybe a Java issue? I am using the latest version of Java.​
