nginx cannot serve React due to permission denied. www-data cant access frontend/build/

I'm trying to configure nginx so that it can serve both React and Django. Here is my configuration:

server {    listen 80;    server_name 182.20.4.110 mydomain.io;    location = /favicon.ico { access_log off; log_not_found off; }    location /static/ {        root /home/ubuntu/myproj_app/static/;    }    location / {        alias /home/ubuntu/myproj_app/frontend/build/;    }    location /apidoc {        include proxy_params;        proxy_pass http://unix:/run/gunicorn.sock;    }

}

However, I keep getting

403 Forbidden

And based on the nginx error logs, it keeps getting permission denied in the React build directory

I tried to change owner to nginx user www-data but still gets permission denied

ubuntu@ip-182-20-4-110:~$ ls -ld /home/ubuntu/myproj_app/frontend/build/drwxr-xr-x 3 www-data www-data 4096 Apr  1 09:47 /home/ubuntu/myproj_app/frontend/build/ubuntu@ip-182-20-4-110:~$ sudo -u www-data ls /home/ubuntu/myproj_app/frontend/build/ls: cannot access '/home/ubuntu/myproj_app/frontend/build/': Permission denied

How can I solve this. I cant serve my React pages with nginx on ubuntu 22.04. And this is on EC2 on AWS setup by someone which I have no control. Could AWS have any settings in the policy to prevent access ?
