I started the apache in the pc , added a domain in /etc/hosts. Then I ran the proxy file, I got the following error : events.js:288 throw er; // Unhandled 'error' event ^ Error: listen EADDRINUSE: address already in use :::80 code: 'EADDRINUSE', errno: 'EADDRINUSE', syscall: 'listen', address: '::', port: 80 Do i need to stop apache?
