RFC_Communication_Failure

[vinayver198]

Hi,

I am trying to make a connection like this
from pyrfc import Connection

def get_connection(connmeta):
"""Get connection"""
print 'Connecting ...', connmeta['ashost']
return Connection(**connmeta)

TEST = {
'user' : 'xxxx',
'passwd' : 'xxxx',
'ashost' : 'xxxx',
'sysnr' : 'xx',
'client' : 'xxx',
'sysid' : 'xxx',
'lang' : 'xx'
}

conn = get_connection(TEST)

After getting executed, it is throwing this error.
pyrfc._exception.CommunicationError: RFC_COMMUNICATION_FAILURE (rc=1): key=RFC_C
OMMUNICATION_FAILURE, message=Timeout while opening an RFC connection. [MSG: cla
ss=, type=, number=, v1-4:=;;;]

Where I am getting wrong ?
Please Help!!

It looks like a network connectivity issue. As a quick check, you may try if the same parameters work from SAPLOGON client, if SAPLOGON available?

For troubleshooting, you may try SAP niping tool and check if niping can reach the ABAP backend, using the same parameters. When niping works with certain parameters set, the PyRFC works as well.

Here few hopefully helpful links:
