CORS – multiple values in Access-Control-Allow-Origin – Apache

I’ve tried to fetch data from WordPress API in Vue App.
I am using DigitalOcean with Apache.

I’ve set Header set Access-Control-Allow-Origin "*" in vhost.

But now I’ve got an error like this:

Access to XMLHttpRequest at xxx from origin ‘http://localhost:3000‘ has been blocked by CORS policy: The ‘Access-Control-Allow-Origin’ header contains multiple values ‘http://localhost:3000, *’, but only one is allowed.

I am using axios for requests.

Do you have any ideas what’s going on?
Is it server side issue or should I set something in axios config?

Thanks.

    This is a server-side issue. You need to enable CORS in your apache config, by either:

    1. Setting Header set Access-Control-Allow-Origin "*" – meaning that all origins are allowed to make requests to this server
    2. Setting Header set Access-Control-Allow-Origin "http://localhost:3000"

    This tells the server to accept requests from this origin(s), to further explain.

    Change your header set statement to:

    Header always set Access-Control-Allow-Origin “*”

    Otherwise Apache will prepend origin in request to the header, which causes the issue.
