For any log subscriptions that are configured to use SSH 1 as the protocol for SCP log push, choose 
SSH 2 instead.

Change the access protocol or add a new SSH 2 key for any users configured to use only SSH 1. Use 
the 

sshconfig

 command in the CLI to make this change. 

Disable SSH 1 using the 

sshconfig > setup

 command in the CLI.
