Hi All,

Getting following exception while connecting to SAP systems.
partner 'host.XXXXXXX:3300' not reached.
ERRNO TEXT WSAECONNREFUSED: Connection refused
I log on to SAP system and I can see the RFC connection are created.

Other than firewall issue,port openings what may be other reason.

Is this a IIB runtime error? Use telnet to the host/port combination is accessible from the IIB server. Also have you added the SAP gateway ports to the /etc/services file?

it was wrong port initially( never mid because that system in Client Scope)
Now we are getting Authorization issue...client can not give full access.
even giving communication level access to user IIB is getting Authorization issues. Not sure which are all the table user access required..or some other setting need to be done in SAP ECC
