Hello,

We are having an issue connecting one of our external applications (SAP PI) to our Sandbox environment using SOAP API.
When the authentication request is sent, the response is successfully returned. Then, when we try to send another request to retrieve updated Contacts, we are receiving the following message in the external application :


When checking the report showing API calls the last 7 days, I see that only one call is added to the Calls count (instead of 2).

Is it possible to monitor with more details the API calls received by SFDC ?
As the error says : Connection closed by remote host, could the external application be denied access to SFDC ?

Best Regards
