+First of all, we need to do all the things indicated here: https://gist.github.com/DevStefIt/23b8971db7e3fe084d29f2c915fb7773
+We need to modify the Nginx configuration file:
+
+`sudo vim /etc/nginx/nginx.conf`
+
+Then, have to add the following lines in the existing RTMP configuration (or create a new one if you do not have it)
+
+```
+. . .
+rtmp {
+        server {
+...
+                application live {
+                        live on;

+                }

+}
+...
+```
+
+We need to configure a block in the `sites-available` folder.
+
+`sudo vim /etc/nginx/sites-available/rtmp`
+
+And insert the following lines:
+
+```
+...
+server {
+    listen 8088;
+
+    location / {
+        add_header Access-Control-Allow-Origin *;
+        root /var/www/html/stream;
+    }
+}
+
+types {
+    application/dash+xml mpd;
+}
+```
+
+Port `8088` is chosen because it is different than the other chose ports.
+
+We enable port 8088 in TCP mode on the firewall
+
+`sudo ufw allow 8088/tcp`
+
+We create the folders of interest
+
+```
+sudo mkdir -p /var/www/html/stream/hls
+sudo mkdir -p /var/www/html/stream/dash
+```
+
+We also grant a reasonable access for the current user
+
+```
+sudo chown -R $USER:$USER /var/www/html/stream
+sudo chmod -R 775 /var/www/html/stream
+```
+
+We reload Nginx
+
+`sudo systemctl reload nginx`
