[bug] Downloading a big package fails with Incorrect Content-Range header

Environment Details (include every applicable attribute)

• Operating System+version: Ubuntu 20.04
• Compiler+version: clang 9
• Conan version: 1.39.0
• Python version: 3.8.10

Steps to reproduce (Include if Applicable)

• Simply trying to run conan install android-ndk/r21d@ yields the error, the download fails, keep retrying and failing the same way.
• The same error happens with a different android NDK package.

This seems similar to #7498 except the package is on Conan center in this case.

I need to remove this from the milestone, as we haven’t manage to reproduce so far. There are many things that can affect here, network issues, proxies, etc, so this might be challenging to solve. I am closing it, as there is little more we can do, but if anyone keeps persistently hitting this issue, or have any possible way to reproduce, please re-open or create a new ticket.

Many thanks to all for all the feedback!

Thanks @jblort If we can reproduce this against the ConanCenter server, removing the client side, that would help reporting something against Artifactory if necessary.
