Unable to connect to Atlas Cluster via mongosql

I’ve tried the suggestions I’ve read but still getting the error in my log file

See the mongosql.config  contents in an previous reply

It’s not accepting my URI. It’s saying "no such host

Here is my log file:

2022-04-21T16:17:02.165-0400 W SCHEMA     [manager] error initializing schema: unable to execute command: server selection error: context deadline exceeded, current topology: { Type: Unknown, Servers: [{ Addr: marty-dev-cluster.cqjnr.mongodb.net:27015, Type: Unknown, Average RTT: 0, Last error: connection() error occured during connection handshake: dial tcp: lookup marty-dev-cluster.cqjnr.mongodb.net: no such host }, ] }
