Unable to reach primary for set when trying connect

Hello, there!

I’m trying to connect my sandbox to follow Connecting to Your Sandbox Cluster from the mongo Shell on m001 course but I got the following error:

2019-05-06T12:35:23.759-0300 W NETWORK [js] Unable to reach primary for set m001-wjb-cluster-shard-0

Is there any chance of this happens to be just a DNS error and in some hours it’ll be solved without further action??

TIA,

WB::
