Explanation
To connect to your WorkSpaces, the network that your Amazon WorkSpaces clients are connected to must have certain ports open to the IP address ranges for the various AWS services (grouped in subsets). These address ranges vary by AWS Region. These same ports must also be open on any firewall running on the client. For more information about the AWS IP address ranges for different Regions, see AWS IP Address Ranges in the Amazon Web Services General https://docs.aws.amazon.com/workspaces/latest/adminguide/workspaces-port- requirements.html#client-application-ports
