Nginx on virtualmin server not working

Hey!

I am trying to set up a VPS with virtualmin and nginx. The problem I have is that everything runs fine, until I create a virtual server in virtualmin with the nginx options enabled.

The steps I take are simple: 1. Install webmin 2. Install virtualmin 3. Install nginx

Until here everything goes fine. Nginx runs, the website returns the standard screen.

However, when I create the virtual server with these options: Enable Nginx SSL website? Enable Nginx website?

Then suddenly nginx is not running anymore. I can not get it started (neither on webmin or virtualmin or terminal). I do get these messages in the error.log:

2015/10/16 14:16:34 [emerg] 31898#0: bind() to [::]:80 failed (98: Address already in use) 2015/10/16 14:16:34 [emerg] 31898#0: bind() to [::]:80 failed (98: Address already in use) 2015/10/16 14:16:34 [emerg] 31898#0: bind() to [::]:80 failed (98: Address already in use) 2015/10/16 14:16:34 [emerg] 31898#0: bind() to [::]:80 failed (98: Address already in use) 2015/10/16 14:16:34 [emerg] 31898#0: bind() to [::]:80 failed (98: Address already in use) 2015/10/16 14:16:34 [emerg] 31898#0: still could not bind()

Googling this shows basically that the port 80 is already in use. Could it be there is a conflict between nginx running on webmin and the one in the virtual server?

Things kind of work by creating a virtual server without the nginx options and configure on webmin. However, this should work, right?

Thanks!
