Your password cannot contain a colon for SFTP
Product refuses SFTP use (or password sync) when the account password contains a colon. Message: change your account password first.
Why this happens
Some SFTP/auth pipelines treat : as a delimiter (login:password style). A colon in the password breaks parsing. Catalog string is locale-mapped; treat the advice literally.
Diagnose and fix
1. Account → Settings → Change password — choose a password without a colon.
2. Reconnect the SFTP client with the new password.
3. See Connect with SFTP / SFTP on storage nodes.
4. Distinct from username and password required (empty fields).
