| - | If ... (from the subject) is a very large number then the problem is typically caused by a message printed from some profile/logon script. It violates an SFTP protocol. Some of these scripts are executed even for [[requirements#configuring_winscp_sessions|non-interactive (no TTY) sessions]], so they cannot print anything (nor ask user to type something). | + | If ...

| To fix the problem, find out, what command in your login script prints the text. Once you find it, move the command to a proper interactive script, or remove it entirely. The scripts are usually hidden (their name starts with dot) and are located in your home directory on the server.
