I was able to use the Port forwarding for Virtual DataPort in the Amazon Web Services instance without any error. If I have come across the "connection timed out" error, I would do the following checks,
* Make sure that both port numbers are included in the Amazon Web Services instance security group.
* Ensure that necessary [ports](https://community.denodo.com/kb/view/document/Remote%20connectivity%20configuration?category=Operation) are open in the cloud instance and on the firewall.
* Try to ping (ping <hostname>) or telnet (telnet <hostname> <port>) from client machine to the server machine by using the hostname configured in the hosts file to confirm if the network connectivity is okay.
* Also, to get more information about the error, I would modify the Virtual DataPort log level as “[Debug](https://community.denodo.com/docs/html/browse/latest/vdp/administration/appendix/configuring_the_logging_engine/configuring_the_logging_engine)’’ in <DENODO_HOME>/conf/vdp/log4j2 and check for the possible causes in the vdp.log file in <DENODO_HOME>/logs/vdp.
For more information, you could refer to the following section,
* [Installation steps on a cloud environment](https://community.denodo.com/kb/view/document/Installation%20steps%20on%20a%20cloud%20environment?category=Installation+%26+Updates).
* [Denodo Platform High Availability in AWS ](https://community.denodo.com/kb/view/document/Denodo%20Platform%20High%20Availability%20in%20AWS?category=Operation).
Hope this helps!
