Failed to connect to instance

Hello,

do you still have the problem or could you fix it by following the linked guide in the error message you posted? https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-instance-connect-set-up.html#ec2-instance-connect-setup-security-group

If you still have the problem, could you post a few details?

• Is your instance launched in a private or public subnet?
• How do you try to connect to the instance (cli or console)?
• Does your securitygroup allow ingress AWS-Instance-Connect Cidrs (if accessing by console)? (see f.e. https://github.com/joetek/aws-ip-ranges-json/blob/master/ip-ranges-ec2-instance-connect.json)
• Otherwise does your securitygroup allow ingress from your ip?
