Troubleshoot problem using SSH automation with Paramiko through existing Python script

I have a Python script using Paramiko to run interactive SSH commands. I can SSH into a Linux server and running commands without any issues, but I have a specific appliance where Paramiko fails to run the interactive commands.

Remote access to the specific appliance will be required to troubleshoot.

Below is the output of the error when attempting to run the script on the appliance:
