HI, All

My head is broken. I'm uploading a screenshot file into FTP server. Android 8. B4A9.3 and now 9.5.
NET lib v.1.8

By TotalCommander FTP-client manually - all is fully OK, via any Internet connection.
But from Android app - the uploading process looks fully OK, but the file is always of 0 size uploaded. This picture file is OK - visible on the screen, in file manager, and on notebook after transcieving, size is not zero.
After uploading B4A9.3 during FTP-listing showed the file size as 0, but now just after update - in B4A9.5 FTP-listing has empty Files() As FTPEntry at all

Any suggestion ?

Passive mode is always.
The test project is attached. The uploaded file is always of 0 bytes.
Please, try with your FTP-hosting, using your host, login and password in ftpsrv service. And subfolder also.

Hmm, also i have found that my Samsung device Android v8 has "VPN Adguard" installed. Maybe it may be a reason ... o_O
