Make package/download: build failed

I am trying to build an image for a Turris Omnia for the first time (19.07), and make download is not cooperating with me.

It first tries to run this command:

curl -f --connect-timeout 20 --retry 5 --location --insecure

and fails with curl: (7) Failed to connect to port 443: Connection refused about 20 seconds later (could be some transient errors on my end): Warning: Transient problem: timeout Will retry in 1 seconds. 5 retries left. This command succeeds when I run it myself from the terminal, so I will deal with that later.

Then the build attempts to download this same file from three locations:

and each is getting curl: (22) The requested URL returned error: 404 Not Found: I checked and those files do not exist there: I think the files in those three locations are prefixed with QCA988X-.

Is there a link missing on the hosting server or this is a build issue?

These are the only files available that match firmware-2-ct-full-community-, so 22.bin is indeed missing.
