I am seeing consistent "Error in uploading file" for files larger than about 15,430 kB.  For 15,300 kB or smaller, no problem, but 15,430 kB or larger always fail.  This is over numerous trials.

My test files, to examine this problem, were generated by Windows fsutil, and are full of null bytes, so I don't think it's a content filter.

I often need to upload larger files, and right now need to upload 3 files that are over 150 MByte (which I have done before several times).

These failure occurred with both Firefox and Chrome.  My cable internet connection tests at about 560 Mbits/s down and 57 Mbits/s up.

My Zoho Wiki account has over 6 GB available space.

Could someone please look into this?  Thanks!
