MII can't find PCo's WSDL

We need MII to use PCo to connect to our OPC server. But when I try to create a new PCoConnector and enter the PCo URL, I get a strange error.

I type this PCo URL:
And I get this error message:
"Error occurred while fetching the PCo agent list; WSDL could not be found for URL http://c111spzbltfth:50050/PCoManagement?wsdl"

The strange thing about this error is that if I simply paste the same URL (http://c111spzbltfth:50050/PCoManagement?wsdl) into a browser, I see a perfectly good WSDL.

PCo is connecting to our OPC server just fine, but we can't create an MII connector to PCo because of this error.

We have:
MII 12.2.3 Build(179) on a Linux server
which connects to
PCo 2.2 (2.200.894.206 Patch level 28528) on a Windows 2008 server
which connects to
FactoryTalk Gateway, an OPC DA server (OPC-DA 2.05a) running on the same Windows 2008 server

I would appreciate any advice. Thanks in advance.

Update: My intial reply was incorrect. We eventually determined that this was due to our not using a fully qualified URL.

This URL works perfectly well in IE:


But for the Linux server on which our MII instance is running, we needed to fully qualify the URL:

This is what eventually solved the problem for us, and many thanks to SAP for helping us figure it out. To answer the question, our ticket number on this was 414824.
