Hi Experts,

The rfc HTTP Connections to ABAP System(XI_INTEGRATIONSERVER) fails with error 'HTTPIO_PLG_CANCELED' in one client while the same rfc connection is executed successfully in other client of the same system.

Program SPROX_CHECK_HTTP_COMMUNICATION fails with the below error message

Hi,

There were Global Proxy setting activated in HTTP services for the specific client in the sap system. Thus HTTP communication was failing.

Now the issue has been resolved.

I believe this is an issue with your ICM parameters.

Whats the value of icm/server_port_0? is HTTP active in SMICM?

Hi Juan,

icm/server_port_0 value is PROT=HTTP,PORT=80$$ and also HTTP service is active in SMICM.

I checked in dev_icm log after executing rfc connection test, i could find the below error/warning message

[Thr 1106856256] Fri Aug 10 16:17:53 2012

10.xx.xx.xx, service: 1090 failed (NIECONN_REFUSED)

Seems like your firewall is blocking the connection.

Check if you can telnet the destination in port 1090. If not then you need to talk to your firewall people as the traffic is been blocked.

Hi Juan,

many thanks for your reply,

But in the same system, when i test the http rfc connection in other client, it is getting finished successfully.

Will the the port be different for different clients in the same system?

btw, i tried to telnet the target server, it was unsuccessful.

telnet 10.xx.xx.xx 1090

Trying 10.xx.xx.xx...

telnet: connect to address 10.xx.xx.xx: Connection refused

telnet: Unable to connect to remote host: Connection refused

Please advice.

Regards

Shanthosh
