SLDAPICUST test failed with HTTP request error (413): NIEHOST_UNKNOWN (-2)


We're setting up connection between an CRM ABAP system and the PI Java.

At first, on the CRM with SM59, we have 2 TCP/IP connections SLD_UC and SLD_NUC, which can work and test successfully. Then we go to SLDAPICUST and would like to create a new connection record. We select "Access to SLD Server Using HTTP" with "Connection Parameter Entered Here", and create the connection, with Alias Name, the PI system address, the workable Port, and User/Pwd which we can use to log into SLD of the PI Java. However, after clicking the "Test" button for this new created record, we get the following failure message:


SLD destination settings:

  Alias:       [my alias name]

  Host name:

  Port number: 99999

  User:        [My user account of PI Java]

Testing HTTP connection to the SLD server...

An exception has occurred:

Exception on SLD server: Error in processing of HTTP request: (413)Connect to failed: NIEHOST_UNKNOWN(-2)

Connection to SLD does not work


There's a very weird point is: the host name "" in the error message is totally different from my host/port settings, which are "" and "99999" (these are not real values, I just give temporary ones here for easier explanation". Because I don't know what the "" is and do not know where it's defined, can anybody kindly help tell me how to resolve this problem?

In addition, we never define "" in the TCP/IP connections SLD_UC and SLD_NUC either. We've treid to search on SCN and Notes but cannot find any solution for this issue.

Any advice will be very appreciated. Thank you very much.
