This install script and config file was used with OVH loaded onto a VM with Ubuntu 20

```
sudo apt-get update
 
sudo apt-get install coturn
set TURNSERVER_ENABLED=1

sudo add-apt-repository ppa:certbot/certbot
sudo apt-get install certbot
sudo certbot certonly --standalone

sudo ls /etc/letsencrypt/live/turn3.obs.ninja/fullchain.pem

sudo apt install net-tools

sudo ufw allow 60000:62000/tcp 
sudo ufw allow 60000:62000/udp

sudo vi /etc/turnserver.conf
sudo systemctl restart coturn
sudo systemctl status coturn

```
and this should go to  /etc/turnserver.conf with the contents below
```
