[Vue.js] CORS - multiple values in Access-Control-Allow-Origin

I’ve tried to fetch data from Wordpress API in vue.js App.
when 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.

when 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?


Solution :

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

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

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