OSMA page cannot be displayed

I have inherited a two server Exchange Cluster (Exch1 & Exch2) with a Dell MD3200 storage array attached to Exch1 and a HAG.  Exch2 is currently the primary server and OMSA is working fine on it.  When I try to load OSMA on Exch1 I get the cannot display page message.  Is that because Exch2 is the primary server?

Why cannot i load OSMA on Exch1? 

Thanks in advance for your help and I apologize for so many questions.  But I am very new to managing servers.  Having to fill in for someone that left.
