I have tried wget --content-disposition --header="API-Key: myapi" -i download.txt . Also tried it manually. I was able to download the files until yesterday without any problems. Could you please help?

Thank you!

What file(s) are you trying to download, i.e. what is in download.txt?

Hi Dylan,

I am having a similar issue. The specific error comes from downloading TNG50-1 snapshot-13 data using the provided wget path. It reads as follows:

2024-02-18 08:53:38 URL:https://data-eu.tng-project.org/file/snapshot/L35n2160TNG/13/57/?token=277aeac3261d5bd79c16 [4430584244/4430584244] -> "snap_013.57.hdf5" [1]

I get the same error at other snapshots such as 50 and 17. Sometimes, when some data is downloaded, after I check on the quality of the download with the also provided file, I get:

sha256sum: WARNING: 47 listed files could not be read
sha256sum: WARNING: 26 computed checksums did NOT match

Which makes me try to download files individually but that has been some work trying to do so for that many files.

Note, I am using screen to run some of these.

If you repeat this command now, are you still having trouble?

For TNG50-1 snapshot-13, I get:
sha256sum: WARNING: 43 computed checksums did NOT match

Do I have to delete all 43 snapshots to run the code again?
I am still getting some errors when I deleted 10 of the erroneous files and ran the command to download files:

In addition, for TNG50-1 snapshot 50, I also get this error when I try to download some individual files:

Hi,

I am having the same issue when trying to download the offset files for TNG50-1-Dark snap 99. I get the error ERROR 403: Forbidden each time I try to download it. Perhaps there is something going on with the site such as updates?

Dylan Nelson

All working now?

It is working for me now! Thank you.

Hi,

I also met similar issues. I want to download the full snap 33 of TNG100-1, and I kept enconutering error 403 and error 503. And when I tried to download the offset (to check my internet), I got error 503. I wonder if someone is doing maintenance or updates to the server?

Dylan Nelson

This appears to just be that the server is busy, because some other people are using it too much.

I will keep an eye on it. Please try again, and let me know if you have further problems,

Some of the downloads seem to be running ok but I still get the following message for TNG300-1 snapshot-99 download:

sha256sum: WARNING: 207 listed files could not be read
sha256sum: WARNING: 33 computed checksums did NOT match

Not sure what to make out of the 207 listed files. In this case, do I just run the command to download the data again?

Also, for reference to everyone: for the 33 computer checksums that did NOT match, I delete those 33 files manually (the ones where the check says FAILED) and then I redownload them. You can do so individually or using the command to download all the data. Since the -nc is in the command, it will only download the files that are missing.
