I am writing a application which connect to a device through ssh and then run a command [which is a .sh script] and store it output. Then create a file of received output in my windows machine.

I am successful to connect and run the command through SSh. All are working fine.

I include libssh library in my .pro file.

But when i close my application i received following logs

[2018/05/18 14:15:43.004000, 1] socket_callback_connected: Socket connection callback: 1 (0)

[2018/05/18 14:15:45.834000, 1] ssh_packet_userauth_failure: Access denied. Authentication that can continue: publickey,password,keyboard-interactive

I googled for these logs but unfortunately did not get any help.

Thanks in advance.
