Well, the issue is resolved now. “Error: Command not found, Command: sft-server-g3” is shown at the because the SFTP user account used for the connection was not provided with read and execute permission over sft-server-g3 (available inside Tectia install directory).

Once the user account was provided with Read and Execute, SFTP connection was successful.
