I have just upgraded my test QlikView server from 11.2 to 12.0
Since that time my working EDX no longer loads and throws the error below.
I don't use Publisher just the standalone QMSEDX.
Do I need to make changes to QMSEDX to run with QlikView 12?
Failed to create a client to the specified Uri.
The message with Action 'http://ws.qliktech.com/QMS/11/IQMS/GetTimeLimitedServiceKey' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
IMHO you have two options:
The v12 version should be published soon (waiting for Qlik approval) but I have not thoughtfully tested it and it is also including ongoing work to make it work with certificates so do not hesitate to send me your feedback !
