Error restoring database: "database may already exist"

Hello, I am trying to simply restore a database after dropping it:

Can you tell me, what am I doing wrong?
Tried both

influxd restore -portable -host=localhost:8088 -db=wiot -newdb=wiot temp_backup/
influxd restore -portable -host=localhost:8088 -db=wiot temp_backup/

The database is empty (no time series data).
