Hello,
Error 79 means Connection Refused.
The "Connection Refused" error means that the host can be reached but the port is not bound on this host. If you check the gateway trace file dev_rd you should find more details on the error, for example
you should be able to see the host and port number involved.
When the problem happens try and connect to the server and port from where the error occurs:
niping -c -H hostname -S portnumber
Also check if the host and port are resolved to the correct value (also on the host where the error occurs)
> niping -v -H hostname
> niping -v -S sapgwXX
If the niping fails, please check the Network for errors and also
ensure that the correct port is used.
Also ensure there is an entry for sapgwXX in the services file.
Regards,
Fionnuala
