I followed the documentation from
https://github.com/coturn/coturn/blob/master/docker/coturn/README.md to set up coturn on docker on my windows server. It has a public ip address. Every time i start the sever, i get the error “You cannot define external IP more than once in the configuration”. I am very sure my config file is correct and i have checked the docker environment variable too but I dont know why this error occurs.
