The domain https://__DOMAIN____PATH_URL__ is free for other apps to be installed on it.
You should close the PeerTube Live TCP port __RTMP_PORT__ available from internet (For example, closing the port on your ISP box if it's not automatically done).
But a futher action is required from your side to completely remove the __APP__ data folder. If you have backup and plan to restore this app in the future DON'T RUN THIS COMMAND.
