Nginx Reverse Proxy Help

Job ID: 31461435

Budget: ₹100 – ₹400 INR

Hello,
I have hosted a project on my VPS using Nginx.
There are two projects running on this VPS -- frontend and backend: on different ports.
I am using reverse proxy to redirect my domain to the port running on my VPS for both-- frontend and backend.
There is a problem while calling the backend domain from the frontend domain (getting cors problem).
I am unable to solve it and need help just to solve this problem.
I prefer a video call or screen sharing for guiding me, rather than providing passwords for my VPS.
For further details we can have a short call.
