I've tried connecting to dropbox account from my AWS ECS instance as specified in this [1] article, but unfortunately I noticed there is a permission problem. The user that I'm using has permission to everything, all out ports are open. Below I've pasted log of failed daemon start.
[ec2-user@ip-10-179-221-31 ~]$ ~/.dropbox-dist/dropboxd
Couldn't start Dropbox.
This is usually because of a permissions error. Storing your home folder on a network share can also cause an error.

Is there a way to use Dropbox on AWS?

It turns out, that it was just a locale problem. The solution is to set LC_ALL and LANG env variables:
[ec2-user@ip-10-111-184-40 ~]$ export LC_ALL=en_US.UTF-8
[ec2-user@ip-10-111-184-40 ~]$ export LANG=en_US.UTF-8
