How to host a React project and an API on the same VDS?

Question

Nginx

Nginx is already installed on the server, projects are placed and running, the
application works on the path /
Api on / api

I noticed that the application does not access the API, after the tests, I realized that the api routes are not being executed.

Is there any solution or article that will describe in detail what needs to be done to make it work?

Answer 1

of course, there is little information, but: check the nginx config first of all (!!!) most likely nginx is configured crookedly for you (because I suspect that you have an attachment and an apishka - these are most likely two daemons on different ports, and nginx proxies it's all on one backend)

Answer 2

Author, would you at least throw some logs, where what requests go from frontend to backend. This is not a forum for telepaths. Imagine how you can answer your question without having information?
Now, if I write to you: "I have a problem, there are no requests from frontend to backend. Nginx restarted."
What do you recommend?
