Port Conflicting Issues

I have been using nginx on Linux ubuntu and everything seems to work fine, I have recently migrated to Mac OSX Yosemite 10.10 and I followed this tutorial

http://blog.frd.mn/install-nginx-php-fpm-mysql-and-phpmyadmin-on-os-x-mavericks-using-homebrew/

to set up my machine, After a lots of hiccups I finally managed to reach a point where I find just a single issue happening due to nginx port issues.

If I do

sudo nginx

I get this


nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:443 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:306 failed (48: Address already in use)
nginx: [emerg] still could not bind()

which means 443 and 306 ports are being used somewhere else

and when I do

sudo lsof -i:443

I get this

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 548 root 13u IPv4 0xce9cf564560ec22b 0t0 TCP *:https (LISTEN)
nginx 549 nobody 13u IPv4 0xce9cf564560ec22b 0t0 TCP *:https (LISTEN)

similarly for sudo lsof -i:306

I get

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
nginx 548 root 14u IPv4 0xce9cf564560ed3cb 0t0 TCP *:306 (LISTEN)
nginx 549 nobody 14u IPv4 0xce9cf564560ed3cb 0t0 TCP *:306 (LISTEN)

Now if nginx is already using these ports, how come it is claiming that Address is already in use

and when I run my app in browser say abc.dev.com

I get no response from server, after sometime browser simply tells me

The connection has timed out


If i do curl http://abc.dev.com I get

curl: (7) Failed to connect to abc.dev.com port 80: Operation timed out




I have ran out of ideas and can't think of anything that could be causing this. Any Ideas are highly appreciated...

thanks for the help
