Hi RayFor

This could possibly be a network or firewall related issue where K2 Connect cannot connect to the SAP server.

Please see the following SAP article regarding SAP NetWeaver port numbers: https://help.sap.com/saphelp_nw73ehp1/helpdata/en/4e/c26cdc58e968b9e10000000a42189e/frameset.htm

From your error it can’t connect to Gateway "sapgw00" and Dispatcher "sapdp00", so from the above article it might be Ports 3300 and 3200.

Regards,

T

Hi ThinusC，

 

From the error message looks like firewall ports issue, but I can confirmed with SAP admin 3300 is the gw service, and even I can telnet the SAPIP:3300 from the K2 connect server. from the detailed log I can see the connection was sucessfully established.

 

Thr 23920] NiIConnectSocket: hdl 4 is connecting to 192.168.81.55:3300 (timeout=60000)

at the bottom of the log it says timeout. do you know the reason?

 

Thank you very much.

Hi RayFor

This does sound like something ouside of K2 Connect, possibly on the SAP side.

A quick search found the following: https://archive.sap.com/discussions/thread/1226806

"We had the same error. Our SAP-System doesn´t open any RFC-Connection although nothing changed. The only thing was we rebooted our server. After this this error occurred.

The solution was to reset the hostname buffer in TA sm51->GoTo->Hostname buffer"

Hope that helps.

Cheers,

T

Hi all,

 

Thanks you, I have resolved this issue, it is caused by sap couldn;t recognize IP, change the IP to host and add some entries in "services" folder, the issue resolved
