5xx or 4xx error with “No 'Access-Control-Allow-Origin' header is present”

Question

My browser is logging the following message in the devtools console:

No \'Access-Control-Allow-Origin\' header is present on the requested resource.…

Answer 1

I had the same issue, the server doesn't support cross origin request. The API developer should change Access-Control-Allow-Origin to * (means from any origin).sometimes jsonp request will bypass, if its not working, google chrome provides plugins to change origin plugin
