curl: (60) SSL: no alternative certificate subject name matches target host name 'ftp.de.debian.org'
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
==> ERROR: Failure while downloading https://ftp.de.debian.org/debian/pool/main/l/linuxdoc-tools/linuxdoc-tools_0.9.73.orig.tar.gz
Aborting...
==> ERROR: Could not download sources.

The certificate is obviously invalid (www.debian.org) doesn't
match to ftp.debian.org.

Works fine with http.

I don't know where to complain upstream (Debian)..
