Had to change instance size on AWS which resulted in an IP Address change. Server was working, but my VestaCP was not, due to change of IP. So following some instructions I found on editing [url removed, login to view] with new IP, I made changes, but nginx would not restart. So now server not online via http.
Need someone who has done this simple task many times to quickly get me back online. Have access via SSH only.
Outcome is simply nginx online and VestaCP connecting.
