  I have experienced the same issue yesterday and after trying the `--use-ftp` argument without luck (this is proposed as an alternative in the forums), I have downloaded the database from [Kraken 2, KrakenUniq and Bracken indexes](https://benlangmead.github.io/aws-indexes/k2) ([ref](https://github.com/DerrickWood/kraken2/issues/753#issuecomment-1692288857)).
