Fatal exception thrown from session ip_address:1028: Only octet transfers are supported at this time.

[JFC-MC]

Hello,

I'm trying to copy configuration file from HP ProCurve switch and it fails with error:
ERROR:tftpy:Fatal exception thrown from session ip_address:1028: Only octet transfers are supported at this time.
I've tried all the options available on the HP Procurve, it didn't help?

Any hope to get this type of transfers fixed soon? Thanks!
