This error generally occurs when the user logs into IGAM and does not wait for the IGAM/FIMS Gateway to open.   The IGAM/FIMS Gateway opens at the same time you select the IGAM/Grants Application Manager to log into IGAM, and adds an icon to your Windows Taskbar.   If you get this message, log into IGAM again, but wait for the Gateway to initiate and add the icon to your Taskbar before entering your Logon ID and Password.  

Note: If logging into IGAM again does not work, make sure you can log into FIMS.   If you are unable to log into FIMS, then contact your System Administrator. If you can log onto FIMS, but still get the error when logging into IGAM, try logging into IGAM on another machine.
