Error "INTERFACE_REGISTRATION_ERROR" between GRC and PI messages exchanges
We are trying to configure GRC communication between ECC 6.0 and PI for NF-e demands. We have created HTTP (proxy) RFC's between PI and GRC for both sides. What's happening is that all messages in GRC appears with "INTERFACE_REGISTRATION_ERROR" in Error ID field, and an error "SOAP: call failed: java.io.IOException: unable to create a socket" in Runtime Workbench for Communication Channel.
Do you have any idea about what is happening?
Thanks and regards,
