403 Forbidden Error for HTTPS Access to Uploaded Files in Nginx on EC2

I'm running an EC2 instance with Nginx configured to serve static files from a specific directory. When I access the files via HTTP on port 4000, everything works fine. However, when I try to access the same files over HTTPS, I receive a 403 Forbidden error.

Here's what I've done so far:

1. Nginx Configuration

   server {    server_name server.avandraapp.com;    root /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public;    location / {            try_files $uri $uri/ =404;    }    # Add Content-Security-Policy header    add_header 'Access-Control-Allow-Origin''*';    add_header 'Access-Control-Allow-Methods''GET, POST, OPTIONS';    add_header 'Access-Control-Allow-Headers''Origin, Content-Type, Accept, Authorization';    location /uploads/ {            alias /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public/uploads;            autoindex on;            allow all;    }    location /api {        rewrite ^\/api\/(.*)$  /api/$1 break;        proxy_pass http://localhost:4000;        proxy_set_header Host $host;        proxy_set_header X-Real-IP $remote_addr;        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;    }    listen [::]:443 ssl ipv6only=on; # managed by Certbot    listen 443 ssl; # managed by Certbot    ssl_certificate /etc/letsencrypt/live/server.avandraapp.com/fullchain.pem; # managed by Certbot    ssl_certificate_key /etc/letsencrypt/live/server.avandraapp.com/privkey.pem; # managed by Certbot    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

}

server {   if ($host = server.avandraapp.com) {       return 301 https://$host$request_uri;   } # managed by Certbot        listen 80 default_server;        listen [::]:80 default_server;        server_name server.avandraapp.com;        return 404; # managed by Certbot}

2. File and Directory Permissions

sudo chown -R www-data:www-data /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public/uploadssudo chmod -R 755 /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public/uploadssudo chmod +x /home/ubuntu/actions-runner-backendserver/_worksudo chmod +x /home/ubuntu/actions-runner-backendserver/_work/tripai-backendsudo chmod +x /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backendsudo chmod +x /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/publicsudo chmod +x /home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public/uploads

1. Error Logs:

[error] 53511#53511: *3 open() "/home/ubuntu/actions-runner-backendserver/_work/tripai-backend/tripai-backend/public/uploads/destination/image/image-1714166321743-183488313.jpg" failed (13: Permission denied), client: 94.187.19.52, server: server.avandraapp.com, request: "GET /uploads/destination/image/image-1714166321743-183488313.jpg HTTP/1.1", host: "ec2-13-53-111-155.eu-north-1.compute.amazonaws.com"

4. Security Groups:Ports 80 and 443 are open in the EC2 instance's security group to allow HTTP and HTTPS traffic.

I'm at a loss on how to proceed to fix the 403 Forbidden error for HTTPS access. Any guidance or suggestions would be greatly appreciated!
