Verify the IAM role has the correct permissions

For an EC2 instance to interact with AWS Systems Manager and establish an SSM session, it must be associated with an IAM role that has the correct Systems Manager permissions which include AmazonSSMManagedInstanceCore policy and any other policy required by the services such as S3FullAccess policy to enable S3 logging. By ensuring the IAM role is correctly configured with the appropriate permissions, you enable seamless integration between the EC2 instance and Systems Manager, facilitating tasks such as patch management, state management, and remote session operations.
