The error states to [::]:80 failed, which means that another process on your system is already using port 80. A port can only be occupied by a single process simultaneously, which means you will either have toclose the process running on port 80 (there‘s several ways on how to check which process is using that port, google it for your OS) orstart using Nginx on another port 80 (which is not recommended, since webservers usually run on port 80).

Answer

The error states to [::]:80 failed, which means that another process on your system is already using port 80. A port can only be occupied by a single process simultaneously, which means you will either have to

close the process running on port 80 (there‘s several ways on how to check which process is using that port, google it for your OS) or
start using Nginx on another port 80 (which is not recommended, since webservers usually run on port 80).

Nginx start failed – how I can repair that problem?
