Error while stepping through Getting Started Guide

Hello,
Trying to follow your Getting Started guide I receive:
$ leaf search -t mangOH

Fetching remote mangOH
ERROR:
Can’t fetch remote mangOH
CAUSED BY:
Expecting value: line 1 column 1 (char 0)
HINTS:
please check your network connection,
or check the remote URL in leaf remote list,
or you can disable the remote with leaf remote disable mangOH
┌─────────────────────────────────────────────┐
│ 0 package - Filter: only master and +mangOH │
└─────────────────────────────────────────────┘

I did some investigation and it turns out downloads.sierrawireless.com is down.
How should I solve this - do you have any mirror server or can you contact SW to fix the problem?
Or edit your guide so the steps work.

Thanks!

what does leaf remote -v show as the URL for the mangOH remote? It should be:
https://downloads.sierrawireless.com/mangOH/leaf/mangOH-yellow.json

Here is what it shows:
$ leaf remote -v

P.S. I’ve split the post to two messages and reformated the links because the system does not allow me to post links.

I just checked the first two jsons are available, but the mangOH/leaf/mangOHyellow.json gives:

An error occurred while processing your request.

Hi,
It is “mangOH-yellow.json” and not “mangOHyellow.json” (a dash “-” is missing):
https://downloads.sierrawireless.com/mangOH/leaf/mangOH-yellow.json

Thank you!
It turns out it is a copy-paste problem from the PDF of my Win machine to the virtual Ubuntu one… the dash was suppressed somewhere in the way.
