unable to connect to cloud instance using SSH

user3620263

Dear,

I just created an instance of CentOS 8, but I cannot connect to it.

The putty client echoes: network error: Software caused connection abort.

I am sure that the IP and the ppk file of the instance is correctly set in putty client.

I tried to connect to the Serial Console Using Cloud Shell according to the guide of https://docs.oracle.com/en-us/iaas/Content/Compute/References/serialconsole.htm#:~:text=bare%20metal%20instances-,Using%20Cloud%20Shell%20to%20Connect%20to%20the%20Serial%20Console,-You%20can%20connect

The connection succeeds. But the Cloud Shell windows prompts a login.

I really don't know the login account & password.

Need your help.

Best regards!

Hey ,

I guess this document will help you - https://devanswers.co/ubuntu-ssh-keeps-disconnecting-idle/

If this works then first set a password for your user , so it can be helpful for troubleshooting in future.
