Scale up as you grow — whether you're running one virtual machine or ten thousand.

From GPU-powered inference and Kubernetes to managed databases and storage, get everything you need to build, scale, and deploy intelligent applications.

I set up the 1 click droplet with Ubuntu and Rails. After setting up Git and uploaded the project I worked on it for some weeks without any problem. Then I did a power cycle from the DigitalOcean web UI and since then I got the 502 error.
I’ve tried everything, rebooting from UI, rebooting from the console, changing permissions on the project to the same user as nginx, rebooting nginx, rebooting unicorn, but until now nothing worked.
Any suggestions on resolving this?
