We are trying to setup an integration between DW and NAV, but get this error when we are calling the service: "Value cannot be null.
Parameter name: cipherText".
We are using DynamicwebConnectorService - 220.127.116.11 and it should be set up ok. including the windows service on the server at the customer.
We can call the service in a browser and get the default "DynamicwebService Service" responsepage.
Using the testapp we do get the expected response when using the "NavService Test"-tab.
But using the "Dynamicwebservice Test"-tab, we get the error, the same happens when trying to test from the site.
Digging aroung i can see the error is thrown when the service tries to decrypt the requst-message, so it looks a bit like that, for some reason, the request-message gets stripped before it hits the connector.
There is no proxy-server infront of the connector, and there should not be anything in the firewall that should block the request.
the shared secret is also ok, as we get another error if we try to change it.
And as we can connect with the "NavService Test", the other settings should be ok.
Does anybody have had this problem too, and know what to do.
I have made quite a few of this integrations before, and have never run into this problem before.
