I have been trying to get this working for about 8 hours. I have created a SOAP Service to try and connect to a list on another SP site. I successfully created the service, using the list and list view GUIDS which seem to be correct. I have tried them like this
c2bcb8cb-29ef-4876-b858-5948604e0bb5 and also enclosed in {}, but didn't seem to matter.
The issue seems to be authentication, because I keep getting the infamous error "The server returned a non-specific error when trying to retrieve data from the data source. I have tried ALL of the authentication types listed in the logon tab. I have tried a Secure Store App, I have tried the App Pool ID, the Farm Account, I tried disabling anonymous impersonation in the webconfig..NOTHING is working. Below is what I keep seeing in the IIS logs
