I am experiencing issues with my Ubuntu 18.04 server running Node 12. Here are the details:

Problem Description:

When attempting to connect via SSH using Git Bash, I receive a “Permission Denied” error.
Upon checking the sandbox server, I encountered the following error: Error: No such container: <container_id> followed by [Disconnected…].
Steps Taken:

Verified the SSH service status and restarted it.
Checked SSH configuration settings (/etc/ssh/sshd_config).
Verified firewall settings to allow SSH connections.
Ensured SSH keys and permissions were correctly set.
Restarted the Docker service.
Checked Docker logs for the missing container.
Current Situation:

The container is not listed when running sudo docker ps -a.
The Docker service is running.
No disk space issues were found.
Questions:

How can I resolve the “Permission Denied” error when trying to connect via SSH?
What steps should I follow to recreate the missing Docker container and ensure it starts correctly?
Are there any additional checks or configurations I should consider?
Any guidance or suggestions to resolve these issues would be greatly appreciated. Thank you!
