I have an EC2 instance in which I am running two scripts one ruby and another python to create another EC2 instance using aws-sdk for respective languages. Boto3 for python and aws-sdk-ec2 for ruby in this case.
Python env
Python Version: 3.8Boto3 version: 1.34.48Python Script
import boto3ec2 = boto3.resource('ec2', region_name='ap-southeast-2')instance = ec2.create_instances( ImageId='ami-0c41a31b32ca4785d', MinCount=1, MaxCount=1, InstanceType='t2.micro', SubnetId='subnet-07330e3514589cb2c1')print("Instance ID:", instance[0].id)Output

instance.
What else should I check in case of ruby?
Update 1
tcpdump for python.
tcpdump for ruby
As you can see I get a Server Hello right after ACK in case of python while I don't receive Server Hello in case of ruby
Update 2
Looks like the issue is with instances using AL2023. It works fine when using AL2.Also it does not work inside a docker container using the image ruby:3.0 on either of the operating systems.
