So this is a friends server, and he was having the same issues as I was. When typing /dl world world, it would compress, fetch the link and say failed to upload file. Is this a temporary thing? I’ve ran into these issues before, but they were all solved within a few days, but this has been going on for a week now. Any help will be appreciated

So i wanted to back up a server i have and successfully downloaded the files, but all the things i had in the nether are gone now. How would i backup the nether? or download it?
