Uppy server companion setting to nginx

uppy_nginx.md

I set this to solve wss error transloadit/uppy#1075

server {
        server_name uppy.xxxxx.com;
        charset utf-8;

        location / {
                proxy_pass http://0.0.0.0:3020;
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

    location /api {
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            proxy_set_header Proxy "";
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_pass http://0.0.0.0:3020;
    }

}
