Hello,  
  
The SSM agent error indicates that it is not able to find the credential to connect and authenticate with SSM APIs endpoints.  
  
On your instance make sure that you have an IAM Role attached or the Credential file (for AWS CLI) configured properly with necessary IAM policy. You may take a look at our below public document about configuring SSM agent:  
http://docs.aws.amazon.com/systems-manager/latest/userguide/ssm-agent.html

This forum is old, but I wanted to provide the reason for my failure in case anyone stumbles on this problem. I was also getting the metadata failure. I noticed I couldn't get to http://169.254.169.254/latest/meta-data/instance-id in a browser either. I had NMAP installed which installs a loopback network device. This network device was set with IP 169.254.x.x with a subnet of 255.255.0.0. So, all requests to 169.254.169.254 were being sent to that loopback device and not to AWS. Disabling the loopback adapter fixed it.

also the error log shows...  
  
ERROR error occurred when starting core manager: Failed to fetch region. Data from vault is empty. Get http://169.254.169.254/latest/dynamic/instance-identity/document: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)  
  
Please any suggestion?

I had the same issue on my hyper-v instance. To get the amazon ssm agent working again I first disabled my hyper-v switch for testing. The SSM agent started right away.
Next I enabled my hyper-v switch and ran the commands here for adding the metadata routes - https://repost.aws/knowledge-center/waiting-for-metadata

Prior to doing anything I ran "Route print" from a command prompt. The metadata routes were there under persistent routes, but they were not in the "active routes" table.
After adding the routes via the above commands my ssm agent service was able to start successfully
