I have SFTP client library[3rd party] which Fails to connect to the sftp server [use password authentication].
From 3rd party log file I can see that SSH/SFTP authentication is successs but ssh channel open is failed hence sftp connect is failing....
3rd party library first creates ssh tunnel and then cretaes a channel and then open a sftp-subsystem
I can see that ssh tunnel is create successfuly , but channel open is failed [server send the channel open failure msg], this may be becuase the user doesn't have ssh access to that server . But I am not sure
I can do manual sftp using command but SSH failed. sftp email@example.com works ssh firstname.lastname@example.org Fails
But why manuly sftp command working fine ?
