Cannot connect to my sandbox cluster

Hi, I am trying to connect to my Atlas cluster but getting the following error. Please help. I get the following messages.

Cannot reach any nodes for set sachin-MongoDB-001-shard-0. Please check network connectivity and the status of the set. This has happened for 1 checks in a row.
Error: connect failed to replica set sachin-MongoDB-001-shard-0/,, :
exception: connect failed

This looks like a connectivity issue or invalid uri/cluster not actually created.

Can you check the connection string you are using from Atlas?

I can netcat to this particular host+port just fine.

I’m afraid you’re now down to basic network troubleshooting.

If not, there’s an issue on your network as @nathan.leniz points out.
