Wireless Access

I have a 7210 Master Controller and accessing the GUI via Chrome. It seems that every few minutes, I get kicked back out to the Chrome page saying "Your Connection Is Not Private" and I have to click through to get access back into the controller. This is extremely frustrating when I am trying to provision APs, only to have it not accept all the work I just did and kick me back out to the login page. 
The controller time and my system time are set correctly, and I don't get this with any other server or device that is on our company's network (even ones that do present me with the "Not Private" message....only the Aruba Master Controller seems to do this. 
The only remedy seems to be to close Chrome and re-open it, then it works for about another 5-10 minutes. This also happens on other PCs, so it is not isolated to just my PC. 

Is there any reason why this does this, or how I can fix it? I really can't do any work on it with it acting like this. 

Are you accessing the controller with a fqdn or with an actual ip address?

Did you import a https:// certificate into the controller with a matching fqdn?
