Forgot change the port setting up nginx...

I had problems getting the php5-fpm to work. So I uninstalled nginx and tried again.
But the second time, I forgot to change the nginx service port, so it was left at port 80...

So now I cant login to OMV!

Where is the file with the port setting for nginx so I can get back in to OMV?
There was a config file in /etc/nginx/sites-enabled (if i remember the whole path) but changing "listening 80" to "listen 8085" and restarting nginx service did not help.

After the server restart I still get I get ERR_CONNECTION_REFUSED. on OMV and when I try to connect to port 8085 I get 502 Bad gateway.
And I interpret that problem to php5-fpm, which I also need to solve before I can use it.

But for now, I would be glad to be able to login to OMV again.

Thanks.

I tried to change the port and got:
"ERROR: failed to load configuration file '\/etc\/php5\/fpm\/php-fpm.conf'"

So I restored an old config file (removing the added php5-fpm references) and that help with the error when I changed the port.
But now I am back at nginx "Bad Gateway".

No matter the port I change to, I get nginx; Bad Gateway.

So it seems I need to fix nginx first. But not sure how.

Ran a couple of checks:
root@nasse:~# netstat -tulpn | grep :80
tcp6 0 0 :::80 :::* LISTEN 12964/nginx
root@nasse:~# service nginx status
nginx is running.
root@nasse:~# service php5-fpm status
php5-fpm is not running ... failed!

So I tried this:
root@nasse:~# php5-fpm -y /etc/php5/fpm/php-fpm.conf

OK, the 591b6465-8ef9-4399-b9da-819e83a6a1da.conf refers to the new pool I added just before OMV disappeared for me. So I renamed that file ("..conf.bak") and now it is working again.
