Trying to reverse proxy to API URL not working

Hi all,

I’m trying to create a reverse proxy for my API url and it is not working. The API is working if I use curl localhost:8800. It is on port 8800. My reverse proxy config is as follow:

server {
	listen 80;
	listen [::]:80;

    location /api {
        proxy_pass http://localhost:8800;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_cache_bypass $http_upgrade;
    }
}

I just keep getting 404 error with this. Please help. Thanks.
