Custom Apache SSHD server messages not displayed by Filezilla, WinSCP and Psftp.exe

Question

I am setting up a custom SSH server using Apache SSHD which interacts with web services, and depending on the web service response the file will be stored or discarded.

Following is my use case:

All users have some limits to upload file into the system.

If user tries to upload a file, i am hitting web service to find the user limits under SSH_FXP_WRITE [6]. If limit exceeds, i am sending SSH_FX_FAILURE and my custom message back to the clients.

The clients are discarding the custom message that i send and just showing the following error:

Error:  error while writing: failure
Error:  File transfer failed

Is there anything that I need to configure at client side or is there any specific message that i need to send so that clients will start displaying the messages.

Do you have any VPN connection that is open concurrently? We found that to be the case with ours. Disconnect the VPN connection and try again.
