https://ftp.de.debian.org doesn't work anymore
on this Monday I could not update Debian testing anymore, since
connection to my preferred mirror fails with the following error:
Err:34 https://ftp.de.debian.org/debian buster Release
SSL: certificate subject name (debian.inf.tu-dresden.de) does not
match target host name 'ftp.de.debian.org'
Indeed, the server has a new let's encrypt certificate. Should Debian or
the mirror server fix this?
P.S. I'm not on the list, please add me in CC.
