Cause

This issue occurs when the client is unable to establish a connection to the server within the timeout period. This may happen due to any of the following reasons:

• There are connectivity issues between the client and the server as a result of network interruptions or firewalls blocking the connection.
• The SSH server has an idle timeout setting that is causing the session to disconnect.
• The SSH server you are connecting to is experiencing problems natively or a misconfiguration is causing the connection to close.
