- Plesk Onyx
For the newly migrated domains, incorrect FTP username is returned via Plesk Multi Server XML API: the service node name is appended to the end of the name.
Updating the FTP username to the correct one resolves the issue.
The FTP username was already existing on another service node during the domain migration.
Plesk Multi Server automatically renames the conflicting system user on the management node is case of system users collision.
Update the FTP username to the correct one at Plesk management node > Subscriptions > example.com > Websites & Domains > FTP access
