Hi Arsalan,
Please note that this forum discussion is to help out general Developer's issue with HANA system, but not for troubleshooting individual's specific issue with HANA setup on AWS or other cloud service provider.
Your issue seems to be with the HANA instance you have on AWS, so it's not a general HDB Studio issue.
I would suggest you to check the SAP on AWS FAQ first:
https://aws.amazon.com/sap/faq/#hana
If you still have technical issue with the HANA server on AWS after reading the FAQ, then you would want to check with AWS Technical support team (AWS Support) who can assist you better with your HANA server issue.
I hope this information helps.
Regards,
Ferry
