Cannot connect atlas cluster to Compass

Region that i am trying to connect to - Mumbai AWS
I am using the free service
I have whitelisted all IPs and uinstalled VPN , ANTI VIRUS , Turned off the Windows Firewall.
The Compass Version that i am using is 1.36.2.

@MR_JINGOIST if I try exactly the same connection string I get an “Authentication Failed” error, which makes sense as probably the credentials in your screenshot are not the actual credentials. So the cluster is reachable? Is it possible that when you posted your message you had not set the access rules but now they are set and things work?
