If you would like to use a different port than port 2020 on your Media Control Panel, you can set it to use an additional port.
We strongly recommend you use the default port 2020 as many parts of the panel utilize this, if you do use another port we also reccomend never disabling port 2020.
You can add another port such as 8080 with the following command:
echo "listen 8080;" > /usr/local/mediacp/nginx/conf.d/8080.conf
Then you must restart nginx:
/usr/local/mediacp/service restart
If you are interested in instead removing the port altogether from your pane URL then you can complete this by following this guide: Remove port 2020 from URL Port 80 / 443 Proxy
