Datatables Working on Local Host but when published to Web app get error 404

Hi,
I have an issue when using aspnet.core 2.1, I have datatables controller for my database which connects to the azure hosted sql server database.
This works fine when using IIS Express Localhost however when I publish the project to a web application I get an the following error,
DataTables warning: table id=example - Ajax error. For more information about this error, please see http://datatables.net/tn/7.
The connection string I am trying to use has windows login and I believe this error may be due to the api request (http post and get) as it says the api url cannot be found error 404 or possibly due to the antiforgery token in the ajax request?
