Error reading SSH protocol banner in aws instance and scp: /home/ubuntu//ros_workspace.tar: Permission denied in gcp

[ghost]

Describe the bug I am trying to build and run this project. I have used Amazon Cloud and also Google Cloud but always getting error.

To Reproduce In AWS

1. Create AWS instance
2. Copy ami and region info

In Google Cloud

1. Create project
2. Build project and run

Also build docker images but still getting errors.

Expected behavior It should build, connect and run.

Amazon cloud in native

Hi Thanks for your interest. My hypothesis is the configuration of firewall/security group that resets the ssh session. Can you try to directly ssh to the machine (get the IP address from the cloud console, with the ssh key in ~/.fogros2/YOUR_INSTANCE_NAME.pem)?
