Hello @MG18,
the best you can do, it so ask your system admin to give a look to the configuration of SAS Environment Manager, in SAS Management Console - Configuration Manager and the DP... web application properties. If you have just Internal connection URL, that would be it, if there is a external one, it could be that you still need to use the internal one, because SAS Environment Manager is normally not accessible from internet, just intranet.
