SCOM2012 Gateway cannot access health service run as account

I just setup a SCOM 2012 gateway server in our acceptance domain but I keep getting this error in my event viewer:

The Health Service could not log on the RunAs account "DOMAIN ACCOUNT" for management group "MANAGEMENT GROUP".  The error is Logon failure: unknown user name or bad password.(1326L).  This will prevent the health service from monitoring or performing actions using this RunAs account

But my gateway server is in an acceptance domain and the runas account he is trying to use is in our production domain. So it is logical that he cannot access this account. What to do? Can I change this account or can I setup multiple runas accounts for multiple domains?

Thanks in advance.
