I got "The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed. " error for an angular 2 application behind nginx server.
Dear experts here:
I am working on an issue raised by our frontend web developer for his angular 2 application. The application is hosted on an nginx server with CORS configured. The Chrome throws an error and says multiple values for CORS. I am attaching the nginx configuration file in the attachment.
