I'm facing a strange issue with the QMS API when requesting data from the QVSServer (GetUserDocuments for example).
Il the network is good enough there is no problem but on a slow network I have strange error messages. You can reproduce ths with QMS API Client (PowerTools) anf Fiddler2. Enable 'Simulate Modem Speeds' in Fiddler2 (Rules->Performance) and send a GetUserDocuments query in QMS API Client.
