Problem solved in the meantime, and leaving a suggestion for product team:
On all your sample AWS templates where you configure Security Group ports, you set TCP allow rules for 257, 18191-18192, 18210-18211, 18221, 28264.
You are forgetting to add 18208: without it
cprid_util -server 10.59.0.28 putfile -local_file /opt/CPcme/features/config-vpn.sh -remote_file /bin/config-vpn -perms 500 with:
data=None
env=None

, fails for not being able to communicate with the gateway.
It would be much better if Checkpoint published real world templates with strict securitygroup and acl rules that documented requirements, than using always "permissive -1 rules" and not documented it properly....
