Review the security group inbound and outbound traffic. If your computer is on a corporate network or if you are connecting through an internet service provider (ISP). Instead, specify the range of IP addresses used by client computers. If your security group does not have a rule that allows inbound traffic add a rule to your security group.

Here's a reference link to
security group rule
