Hello, today i made a snapshot doing everything what is written in documentation., i turn off droplet in terminal and then successfully made a snapshot. In documentation there was written that i need to wait and it will restart my droplet, but it wont power it up again, so i did it manually. Okay snapshot i made and everything seems to work, then i try to access my site but i get error;

502 Bad Gateway
nginx/1.4.6 (Ubuntu)

I already send a ticket to Digitalocean but maybe someone else know where is the problem ?
