The adress I connect to display Welcome to nginx, not pufferpanel.
Pufferpanel is not showing up, I installed puffer, but no panel! Only nginx.
you should of had to create a domain for puffer panel, if you use the direct IP or the IP assigned to nginx itself you won't get to the panel. If you are unsure as to what the domain is you could have a peak into the nginx config to see what its domain/servername is :)
