PyRFC Connection call issues about pyrfc HOT 6 CLOSED

The error key RFC_COMMUNICATION_FAILURE indicates a network problem, happening during opening the RFC connection. It usually happens because the RFC connection can't be established using given connection parameters.

Error keys are described in NWRFC SDK Guide and in sapnwrfc.h include of the sapnwrfc lib.

SAP troubleshooting utility niping can check the network connection, from the system on which the Python client is running, to ABAP backend. It works independent of pyrfc and if the niping test is positive, the pyrfc should open the connection as well, without errors. The link to SAP Help I posted in issue #43.

Could you please post the error text you are getting ?

I have the same error
The code I write:
from pyrfc import Connection
conn = Connection(user='my_name', passwd='my_password', ashost='my_ip', sysnr='00', client='100')

and I got that error;

is this mean that the problem related to the server or related to the installed pyrfc function ?

Thank you for your quick response.

Hi @bsrdjan can we make a RFC call from pyrfc to sap logon even if we don't have sap logon installed in our system. And in sap do we have to add the ip address from which we are going to send the request??

from pyrfc.

pyrfc call goes from client system like notebook, to ABAP system. Nothing to do with SAPLogon. No IP addr needed:
