Failed to upload File <file>. Unexpected result code:

We have an external client accessing RTC through a proxy server (partnerconnect.b2b.pok.ibm.com). They have no problems creating and loading a repository workspace or create change sets however, when attempting to check-in files, they get the following error message:

"Failed to upload file <filename>. Unexpected result code: 200"

The client's Eclipse .log file shows the following when check-in is attempted:

!ENTRY com.ibm.team.filesystem.client 4 0 2011-06-22 16:00:09.148

No errors seemed to be found in the jazz.net or WAS log files. Still waiting to get my hands on the proxy server log files to see if there are signs of the error within.

Any assistance in this matter is greatly appreciated.

Thanks,
