I know this question a bit weird maybe but it’s the first job i have and I found myself in a project with many open source solutions and mender is just one of them. I’m just trying to understand what’s going on.

Best regards

It was dissolved. I got an error when I tried to enter my server address because there was another application using 9000 port. So must be filled with server address.
