Yesterday the api was fine but today it gives me cors error ?

What is your host name.

Only localhost is allowed

localhost:3000 :( zeevy please help me i have a case study from a company. I have to use your api and complete the project in 2 days but im getting error now.

Access to fetch at '' 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. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

access-control-allow-origin: http://localhost:3000 is allowed

are you using wrong url "" instead of ""
