Hi @parnaz-pirhadi I also faced same issue.

Actually in this code there are two phase that is : client & server.

You have to npm start both the folder and change the Endpoint (as shown in image, in Chatjs component)

The issue is because the "https://project-chat-application.herokuapp.com/" host might be inactive, that's why it is not accepting response.

for me changing the Endpoint worked, and I came across new bugs!!

Happy coding

socket.io has changed its documentation. You can refer to this page https://socket.io/docs/v3/handling-cors/

Or check my repo https://github.com/Lagnajit09/realtime-chat-app.... I have used the latest version and it works perfecttly
