It does try a number of mirrors:

D:querying mirror, got 'https://ftp.snt.utwente.nl/pub/software/tex/'
D:querying mirror, got 'https://mirror.koddos.net/CTAN/'
D:querying mirror, got 'https://mirror.koddos.net/CTAN/'
D:querying mirror, got 'https://mirror.lyrahosting.com/CTAN/'
D:querying mirror, got 'https://mirror.koddos.net/CTAN/'
D:no mirror found ... randomly selecting backbone
Loading https://www.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb

but is not happy with any of them.

With both syntaxes, I get an actual mirror:

C:\Users\siepo>curl -Ls -o nul -w '%{url_effective}' https://mirror.ctan.org/
'https://ftp.snt.utwente.nl/pub/software/tex/'
C:\Users\siepo>curl -Ls -o nul -w %{url_effective} https://mirror.ctan.org/
https://mirror.lyrahosting.com/CTAN/

For completeness, I attach the logfile.
