I added the Host key to the script and it seems to have fixed the problem. I haven't had a failure since I added this. I really appreciate your help with this.

Yes, I was talking about the GUI.

Again, thank you for the help

I currently don't have a copy of a successful connection. I didn't start the scripting process until just the other day after 4 failures in a row. My bad. But, my question is, why would it always connect via a manual terminal session using the Commander interface (that I have a script of) and not a scripted session?

Re: Scripting Automation Sometime works sometime fails

You are not verifying the server host key in the script.

So I wonder how comes it works sometimes at all.
Please attach a complete session log file from both successful and failing session.

Scripting Automation Sometime works sometime fails

I hope someone can help me. I have a script that sometime will work fine for days and then it will suddenly stop working. Based on the log (see below) it has a connection issue. When I run the Commander interface the same connection works fine every time. I have provide the script I call and the last part of the log file that appears to show the connection issue. If more of the log file is needed, it can be provided.

Script:

option batch abort
option confirm off
open sftp://UserName:Password@somesite.com/
put C:\ClientProjects\ClientName\FTP_Files_To\*.to /ClientName_TO_2016/
exit
