Yurii Kartsev commented on VFS-317:
-----------------------------------
Your fix works, but fixing the system type does not, because it fixes something
wrong which results into "file does not exist". Maybe the workaround adds an
option which the file doesn't have and therefore it can't be found?
File name can't be a problem, because I've tested it on simple FTP and it works
well.
The log shows nothing unusual:

> Using the built library I've managed to successfully connect to FTPS server,
