Yes, it was just the only thing somehow related to pacman that changed
on my machine. The issue not necessarily caused by my computer.

I can't, since the issue disappeared.

Btw. using a browser downloading worked without any issue, too and
without any notification.

When the issue happened I run "wget" also without the quite option. I
was in a hurry, doing several things in parallel. There was no error
message, but this morning I had the feeling I missed/ignored a
notification about a certificate provided by the output of "wget". When
I repeated downloading with wget, there was no such a message, but
"pacman -U URL" for this package, from this particular server worked in
the morning, too. I wish I would have posted wget with output.

Now it's too late for troubleshooting, the issue is solved.
