How to fix error "The service... /listdata.svc does not exist"

Question

After upgrading from sharepoint 2013 to sharepoint 2016 ( using the database attach and upgrade method), one of our developers is unable to call the listdata.svc to get data from a sharepoint list If the developer tries to access the listdata.svc direct, they get asked for credentials and after entering their windows credentials they get a 401 unathorized error. We can see errors in the event log as per below

WebHost failed to process a request.

 Exception: System.Web.HttpException (0x80004005): The service '/Site1/listdata.svc' does not exist. ---> System.ServiceModel.EndpointNotFoundException: The service '/Site1/listdata.svc' does not exist.

Hi @Greg Booth

You can enable includeExceptionDetailInFaults to get more response of the error message. Database connection also cause the issue. Please check the status of your database. And I found a similar issue with yours, please make a reference
