quick update: today I tried "tlmgr update" with the new 2020 installation,
and tlmgr *does* show the same problem with that specific web proxy!

so something changed in the perl code how to acceess web files through a proxy between tl 2019 and 2020,
all updates will suck in such a configuration:-(

how can I help debugging/understanding why now I need "-no-persistent-downloads" for the very first time,
why all other tools/programs do not show similar issues ?

thanks for any hint/help,
