 Set up nginx / a reverse proxy and point it to the web app.
 
+Make sure it allows WebSocket connections through, for example:
+
+```
+server {
+    root /var/www/html;
+    index index.html index.htm;
+    server_name upload.example.com;
+
+    listen 80;
+
+    client_max_body_size 100M;
+
+    location / {
+        proxy_pass http://127.0.0.1:8080/;
+        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;
+
+		# websockets
+		proxy_http_version 1.1;
+		proxy_set_header   Upgrade    $http_upgrade;
+		proxy_set_header   Connection "upgrade";
+		proxy_redirect     off;
+    }
+}
+```
+
+Then restart nginx and set up HTTPS:
+
+```
+$ sudo service nginx restart
+$ sudo certbot --nginx
+```
+
