Unfortunately this does not help. After today's infra update with the generic 
address I get:

| /usr/local/texlive/current/bin/x86_64-linux/tlmgr: signature verification 
error of
| /usr/local/texlive/2021/tlpkg/texlive.tlpdb.main.

cryptographic signature verification of 
|   /tmp/u23nQVXiXG/m4lwylA0kJ
| against
| failed. Output was:
| gpg: Signatur vom Tue 20 Apr 2021 01:53:17 CEST
| gpg:                mittels RSA-Schlüssel 4CE1877E19438C70
| gpg: FALSCHE Signatur von "TeX Live Distribution <tex-live at>" 
| Please try from a different mirror and/or wait a few minutes
| and try again; usually this is because of transient updates.

and every https mirror (I've tested several German mirrors, e.g. uni-erlangen, 
oth-fulda, gwdg, oth-regensburg, fau) fails with:

| /usr/local/texlive/current/bin/x86_64-linux/tlmgr: cannot download: download 
did not succeed: Germany

The only German mirrors that work are the ftp access to mirror (which seems to be outdated) and the 
http access to

So either all the mirrors I've tested are broken (but e.g. usually gwdg and 
uni-erlangen are very reliable) or the https access does not work.
