AMI creation on AWS getting failed with status code: 401

Packer
1

i am using packer version 1.5.5 and trying to create AMI on AWS but getting an below error:

" Build ‘amazon-ebs’ errored: error validating regions: AuthFailure: AWS was not able to validate the provided access credentials
status code: 401, request id: a06b49b4-4ee1-42c6-99a5-7cd9f62d3387"

i have already exported the aws secret, access and the region on the packer node. is there anything which i am missing.

in aws i am able to create the AMI using the same account which i am using in the packer json.

I am able to resolve this error by performing the below steps:

yum install ntp -y
service ntpd stop
ntpdate time.nist.gov
service ntpd start

hope it helps to other people facing the same issue.
