Missing digest header in POST request when commiting large file upload

[chowderhead]

greetings,
i own a registered copy of cyberduck and have encountered a error that i cant figure out. please analyze my error log and advise what i should do.

the error occus only using the api.box.com. FTP uploading to ftp.box.com works fine to box. downloading from api.box.com works fine, uploading does not. I can find no workaround. uploading one file or multiple makes no difference. same error.

my debug log is attached.

cyberduck.log

BTW im using version 8.5.9.(39636) on windows 10 Enterprise LTSC build 17763rs5 release 180914-1434 on a comcast business internet 200Mbit DL/30Mbit UL connection. I also am able to successfully UL to api.box.com with filezilla so i know its possible with my PC just NOT with cyberduck. filezilla has other things i find annoying not related to uploading which is why im looking for alternative applications currently and subsequently tried cyberduck.
thanks
Randy
