I am following the steps mentioned in openvidu documentation to setup Coturn server on seperate machine.  
Machine is having public ip. Basically it is Azure ubuntu VM.  
The link i am using for reference is : [Allow users behind firewalls - OpenVidu Docs](https://docs.openvidu.io/en/2.22.0/deployment/allow-users-behind-firewalls/)  
I am following the section **" Deploy a TURN service for clients behind firewalls (with Let’s Encrypt)"**  
But when i execute command : **docker-compose up -d** , it gives error :  
ERROR: for coturn Cannot create container for service coturn: Conflict. The container name “/coturn” is already in use by container "4b79247cf361bf8a9f07c30414a25e381cStarting certbot … error

Please help to resolve this.

You have some other service running on port 80. Certbot requires that port.

I checked, no service is running.  
I have done fresh installation.  
But when i run below command -  
docker-compose logs -f  
It is generating following logs -
