Bex analyzer connection problem

Question

hello
i have a problem when i want to connect from excel with the bex add-on to the application server. i geht the following error:
RFC_ERROR_COMMUNICATION
Nachricht
CMALLC : rc=20 > Connect from SAP gateway to RFC server failed
Connect_PM  GWHOST=extgateway.XXX.at, GWSERV=sapgw01, SYSNR=01

COUNTER
the connection should be established over the internet.
external computer -> internet -> gateway -> sap application server
the gateway is configured to foreward the ports 3201,3301,3401 and 3601 to the sap server.
when i open excel by using the transaction rrmx then the connection is established correct and i can work without any problems. also sapgui works correct over the internet.
maybe someone can help me.
thanks in advance

Answer 1

Joachim,
Did a search for your error on the internet-
or error WSAECONNREFUSED (10061)
   1The remote host actively refused the attempt to connect to it.
   2.Verify that the destination server name or IP address is correct
   3.Verify that the connection port number is correct (under Site Settings | Type tab).
   4.The remote server may be temporarily or permanently inaccessible (try again later).
   5.Verify that you have chosen the right protocol (SSH2, SSL, FTP, etc.) and have setup all required options for that protocol.
   6.Verify that the destination IP address and port numbers are correct.
   7.The remote server may be refusing multiple connections from the same client. Try using only one connection thread when connecting to this particular server (Site Settings | Options).
   8.Try pinging the address.
   9.If you are using a router, verify the router is up and running (check by pinging it and then ping an address outside of the router).
  10.Do a traceroute to the destination to verify all routers along the connection path are operational.
  11. Verify that your subnet mask is setup properly.
Looks like a winsock error - check if there is any service to declare on the hosts / services files
Are you using a router string in your GUI ? This may not be the issue - but possible issue could be that the SAP server is treating this as an RFC connection which is not coming through trusted channels.
What is your Frontend SP level - upgrade to the latest available and usually when you start BEx without any BI login also on the same client - there is a dummy window opened by BEx for the SAP GUI to achieve this...
Some pointers - but not sure what could be happening...
