Unable to download and install Kneaddata database

Hi, I am bumping this thread since I also can’t download the database,

I just installed the conda version (kneaddata v0.12.0) with mamba and did the following

kneaddata_database --download human_genome bowtie2 KNEADDB

I got this critical error

Download URL: http://huttenhower.sph.harvard.edu/kneadData_databases/Homo_sapiens_hg37_and_human_contamination_Bowtie2_v0.1.tar.gz
CRITICAL ERROR: Unable to download and extract from URL: http://huttenhower.sph.harvard.edu/kneadData_databases/Homo_sapiens_hg37_and_human_contamination_Bowtie2_v0.1.tar.gz

I even tried aria2c as a workaround as suggested here…

I also tried to manually downloading this this wget… and got

ERROR: El certificado de «huttenhower.sph.harvard.edu» no es confiable.
ERROR: El certificado de «huttenhower.sph.harvard.edu» no tiene un emisor conocido.

so I guess it is a server issue…

Thanks for your help
