Hi guys, Deployed the datasync agent on-premised (Vmware environment) successfully and did the "Test Network Connectivity" to AWS DataSync which is also successful.

You can get an activation key directly from the local console on the VM itself, following the instructions here: https://docs.aws.amazon.com/datasync/latest/userguide/local-console-vm.html#get-activation-key. You can then use this activation key when creating your agent in the AWS Management Console for DataSync.

Can you verify the following

• Check that host has the correct time and that host is configured to synchronize its time automatically to a Network Time Protocol(NTP) server and that VM has the correct time. For information about synchronizing the time see https://docs.aws.amazon.com/datasync/latest/userguide/local-console-vm.html#time-management
• Check if there is an existing VPCE endpoint. If yes then it will give this error when trying to activate using public endpoint.
• Check that there is no SSL or deep packet inspection within on-prem firewall as this can also cause activation to fail even though network connectivity tests show as PASSED.
• You can also check the connectivity on below endpoint using telnet or any another connectivity command.
