So basically CORS protocol is present so someone cannot send requests on other sites, while loading your site (you've got your bank account open on the other tab, then you load another site which sends a command request to the bank's URL to transfer money for example. browser prohibits that under this protocol CORS)

The server you're connecting to has to allow (i.e whom ever is answering at this end: 'http://localhost:2283/Help/api/Member')

And there is a good manual to guide you through depending on what web server you're using: https://enable-cors.org/server.html
