The Application Was Not Able to Load

[MaxReichart]

Hello,

I have a Network Management Card 2 (model ap9631) which is throwing that error:

The Application Was Not Able to Load

You are attempting to access a Schneider device.
There was a problem loading the application. Please login to the device via telnet for more details.

Nothing was changed, all of a sudden that error appeared.

I tried:

Updating via NMC Firmware Update utility (FTP/SCP), get the following error: Firmware distribution does not match target device platform; this could be due to a corrupt distribution.

Updating via SSH, was not able to transfer the firmware file in advance via FTP (error)

Resetting via SSH:

apc>resetToDef –p keepip
Usage: resetToDef -- Configuration Options
resetToDef -p <all | keepip>

-> Just throws me the result above (My command is correct :/)

The about (Terminal):

E000: Success
