File Transfer

SUMMARY
Copying any larger file than 3GB will stall. See video. I was trying to copy files to my SFTPGo Server. Using FileZilla or the built-in WebApp works.

STEPS TO REPRODUCE
1. Have a local SFTPGo server
2. Login on Dolphing to that server
3. Copy any large file (fallocate)

OBSERVED RESULT
See video. After exactly 3067207680 bytes the transfer over LAN abruptly stops.

EXPECTED RESULT
The transfer keeps going, as seen in FileZilla.
