I am using Restify in my Heroku server. I am getting this error:
XMLHttpRequest cannot load https://xxx.xxx.com/charging. Response to preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested resource.
Origin 'http://xxx.xxx.com' is therefore not allowed access.
The response had HTTP status code 405.
My Restify configuration is:
server
.use(restify.fullResponse())
.use(restify.bodyParser())
.use(restify.queryParser())
.use(restify.CORS({
origins: ['https://xxx.xxx.com', 'http://xxx.xxx.com']
}));
What is missing in my configuration?
In some cases, you may need to use server.pre instead of server.use.

I'm getting this error trying to add Microsoft 'New Store' app function in Intune. I tried getting help from Microsoft, but they were no help.
Using Edge and Chrome , both give the same result. My pc has been rebuilt, I reset Edge & Chrome's browser settings, history and everything I can think off. Still have the same issue.

My problem is CORS is not constant.
My React Project request api server and works well.
But sometimes api server response this error
Access to fetch at 'https://api.example.com/' from origin 'https://example.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
Why same client request sometime response cors error?
Please Help.
On local development I am facing following error on ajax request:
Access to XMLHttpRequest at 'http://pmb.local/jsonapi/product' from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.
Need to the following change this this file
Ddont forget to run:
php artisan optimize
I am pulling in an Iframe that has javascript included in it. I have installed the fruitcake cors package and set the config file to be wide open. I also added the "Access-Control-Allow-Origin' header to the xmlhttp request just in case because I am confused on who is actually denying the request. Here is the error I am getting -
Access to XMLHttpRequest at "https://site-that-i-am-posting-to" from origin "https://where-the-iframe-is-sourced-from" has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present of the requested resource.
Figured it out. I needed to add the correct request headers to the xmlhttprequest like this -
xhrapi.setRequestHeader('Origin', 'https://site-posting-from.com');
xhrapi.setRequestHeader('Access-Control-Request-Method', 'POST');
And then it worked. Thanks to anyone that tried to help!
I tried to post a request to my Laravel backend but failed to get the response as the error "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost:8000/path. (Reason: missing token ‘access-control-allow-origin’ in CORS header ‘Access-Control-Allow-Headers’ from CORS preflight channel)" showed.
I have added Access-Control-Allow-Origin and Access-Control-Allow-Headers in both my client and server. Why does the error still showing?
Remove the client-side code you added to send Access-Control-Allow-Origin in the request.
(Reason: missing token ‘access-control-allow-origin’ in CORS header ‘Access-Control-Allow-Headers’ from CORS preflight channel)" showed.

The error is showing because you added an Access-Control-Allow-Origin header to the client-side request. But Access-Control-Allow-Origin is a server response header. So if you send it from the client side in a request you’ll see the kind of error you’re seeing now.
“missing token ‘access-control-allow-origin’ in CORS header ‘Access-Control-Allow-Headers’“ is the browser telling you that your client code is sending an Access-Control-Allow-Origin request header, but the Access-Control-Allow-Headers response header the server has returned doesn’t list "Access-Control-Allow-Origin" as one of the header names it allows in requests.
So because of that, the browser isn’t letting your frontend JavaScript code read the response.
