Hello,
I seem to be having an issue with v5 that I could do with some assistance with. It has been doing it for a while which made me think that is was the SFTP server or work proxy being the issue, but using v4 or WinSCP I don't get the issues.
The issue I am getting is :
[L] SSH Error: (105)
[L] SFTP Connection closed
[L] Download Error: Connection closed by lower level protocol
[L] SSH Connection closed
It happens randomly while in the office (on 50mb+ files), but all the time over VPN. (1mb+ files).
v4 and WinSCP seem to happly download without any errors, I tried to match v5 with v4 settings but couldn't get the fingerprint part to match, both using SFTPv3.
From v5 :

It will then reconnect and try again giving a different error :

I have played around with various settings in v5 but get the same results.
If you need anymore information, let me know!
Kind regards,
