550 Not found when logging in
Why a brand-new service or user sees "550 Not found" on their first FTP login, and the one-step fix.
Updated August 27, 2026Right after creating a service or a new user, the first FTP login can fail with a 550 Not found error.
Why it happens
On login, many FTP clients immediately ask the server about the user's home directory. Object storage backends have no real directories - a "directory" only exists once something is stored under its path - so a brand-new user whose home directory has never received a file gets not found.
This is the empty-directory quirk of object storage; see Cloud storage limitations for the family it belongs to.
The fix
Upload any file - the home directory springs into existence and the error never comes back.
Alternatively, create the directory on the backend first:
- S3 and Google Cloud Storage consoles can create empty folders directly.
- Azure cannot - upload a file into the new directory to create it.
