VPSSIM appears to be an auto installer script with multiple options. Default is for ports to be open and I see a default NGINX page at the IP address provided. When you say you tried all commands what were these?

You can see what ports are open and their associated programs using something like:

netstat -anp

from the command line. Check your firewall configuration with

sudo iptables -L

On most systems default is ACCEPT, but might be different with the installer you used.

Same situation here. I have installed a Wordpress app with the one-click auto install and I tought everything would work out of the box. It’s been 2hs since I started to try enable port 587 for outgoing mails, seems to be working as I can telnet to the port, but php (wordpress) fails to send mails.
