Deploy Strapi on VPS

Hi

I’ve followed all steps here (How to Deploy Strapi to Your Own VPS).

When starting the server using “NODE_ENV=production forever start server.js” the server runs but i cannot access my strapi app on the front end. the address is http://88.208.196.88:1337/admin

the page just times out and errors " This site can’t be reached"

What is the solution for this?

thanks for your advice.
