Thank you for the reply and link. Apologies, few more queries on it: In the section: 'Ports for client applications', there is 443 port which says it should be open for This port must be open to the following IP address ranges: The AMAZON subset in the GLOBAL Region. The AMAZON subset in the Region that the WorkSpace is in. The AMAZON subset in the us-east-1 Region. The AMAZON subset in the us-west-2 Region. The S3 subset in the us-west-2 Region. Query: Do we need to open for all even if we need it for one region where workspace is in? Another query on Management interface ports: The following ports must be open on the management network interface of all WorkSpaces: -- are these changes in AWS environment??
