Unable to create F5 in AWS via CFT - no internet access

Now I am getting Startup success, nothing in logs, just rollback after some time.  Seems to be problem with Declarative onboarding ....

024-10-10T13:04:18.768Z [13232]: silly: ipcalc function resolved first element: 172.31.1.1 of provided IPv4 CIDR
+ [[ 1 -eq 0 ]]
++ date +%Y-%m-%dT%H:%M:%S.%3NZ
+ echo '2024-10-10T06:04:28.686Z : Startup Script Finish'
2024-10-10T06:04:28.686Z : Startup Script Finish
+ rm -f /tmp/6337.tmp

And error CFT: The following resource(s) failed to create: [Bigip2NicInstance].

Failed to receive 1 resource signal(s) within the specified duration

It might be failing on activation of license. Based on https://github.com/F5Networks/f5-aws-cloudformation-v2/blob/main/examples/DEPLOYMENT-TRAFFIC-FLOWS.md how did you achive to reach the activation portal?

But the PAYG template is not even having the license part in YAML, so not the case here.

Thank you
