Compass when connecting to Cluster

Hello,
I am trying to connect to my Database Cluster(Compass when connecting to Cluster), but I get the following error:
“connect ETIMEDOUT 52.206.44.20:27017”
Please see screenshot below. Any ideas how to fix this?

thanks

Can you connect by shell?
What connect string you have used in your Compass?

Same issue happening with me. When I try to connect to cluster it does not connects and show the message “connect ETIMEDOUT 13.234.235.198:27017”

Somehow when I changed the internet connection it worked. That means the openDNS is causing the problem.
