Bad GET Request Result - eTag Error

I am having an issue where the 'rm/oslc_rm/catalog' is being queried but resulting in the requesting program throwing an error related to the eTag and a missing semicolon.  Is this an issue on the DNG side or the requesting tool side?  We have multiple instances of both DNG and this tool and the tool is only having this error in one instance (versions of both tools are the same in both instances where it succeeds and where it fails)

If a DNG issue, how to fix?
