When downloading the snapshot data of snapshot 99 for TNG50-1 many files give either Error 403: forbidden or Error 503 Service unavailable; First I used the bash command created by the website. When this did not work I was recommended to use wget -c -nd -nv -e robots=off -l 1 -r -A hdf5 --content-disposition --header="API-Key: my API key" "http://www.tng-project.org/api/TNG50-1/files/snapshot-99/?format=api"; still the same problem; i also tried the download with a newly generated API key, still no success. The out put always looks something like:
