Unable to authenticate through upload

[Predrag Punosevac]

Something is happening with the gateway machine. Your report was right on
money. I am having a hard time logging in even with the root account. I am
trying power cycle via IPMI. If that doesn't fix the issue I will have to
look into it later today when I have the access to the hardware.
