Nvidia developer files server is down?

Hello,
I am trying to download the Jetpack 4.5.1 for Jetson OS. Currently the SDK manager failed to download a lot of files, for instance:

10:58:36 ERROR: Drivers for Jetson - target_image: command terminated with error
10:58:36 SUMMARY: File System and OS - target_image: Depends on failed component
10:58:36 INFO: File System and OS - target_image: stopped downloading https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.5.1/JETPACK_451_b17/T186/Tegra_Linux_Sample-Root-Filesystem_R32.5.1_aarch64.tbz2

Upon visiting this url https://developer.nvidia.com/assets/embedded/secure/tools/files/jetpack-sdks/jetpack-4.5.1/JETPACK_451_b17/T186/Tegra_Linux_Sample-Root-Filesystem_R32.5.1_aarch64.tbz2, a placeholder message like this is shown:

Heroku | Welcome to your new app!
Refer to the documentation if you need help deploying.

Am I the only one experiencing this issue ?

The log shows the URL as part of the SDK Manager running, and if I go to that URL manually, I get the same thing. Are you actually trying to download 4.5.1 from a browser? If so, then most likely you’d want to use the most recent JetPack/SDKM, and start it with option “--archivedversions” like this:
sdkmanager --archivedversions

There is also this URL for all listings of JetPack/SDKM versions:
https://developer.nvidia.com/embedded/jetpack-archive

I haven’t actually tried downloading that just now, but in theory you could get the specific release through that URL after clicking on 4.5.1. What I’m really interested in knowing is if running an SDKM resulted in needing that URL, versus if some web page directed to that.

The log came from SDK Manager, I have attached a screenshot, thanks !

The problem is gone, as of today. Not sure why it happened and why the problem disappeared.

There was probably some cache or DNS issue. Often those take a day or even three days to propagate changes out.
