AP9631 FTP Fails at 100%

[jackjprice]

Hello,

I am attempting to automate the firmware upgrade process on our APC UPS. When I put the firmware file on the UPS using FTP, it fails at 100%. I have tried a couple different avenues and I will include the errors below.

Command Prompt:

Connection to [ups] closed by remote host.
C:/File/SRT1020UPS_15-9.enc: Broken pipe
apc-scp: file save error

Python - FTP:

Transferred 1533696 bytes: 1533696
*get* '426 Connection closed; transfer aborted.\n'
*resp* '426 Connection closed; transfer aborted.'
FTP Error: 426 Connection closed; transfer aborted.

Python - SCP:

OSError: Socket is closed

I am able to get and put smaller files from the UPS using FTP and SCP.

Here is some information about my UPS, but this does happen with other UPS that have AP9631/9630 NMC.
