Hello,

I have noticed that having zone configs, be it auth-zone or rpz-zone, using a 
HTTP/S-URL fails silently unless the log verbosity is increased.
Trying the same download via cURL works on my bullseye system.

Example config:

rpz:
    name: abuse_ch_threatfox
    zonefile: abuse_ch_threatfox.rpz
    rpz-log: yes
    rpz-log-name: abuse_ch_threatfox
    url: "https://threatfox.abuse.ch/downloads/threatfox.rpz";

Log excerpt:
debug: auth host threatfox.abuse.ch lookup 151.101.114.49
debug: auth zone abuse_ch_threatfox. transfer next HTTP fetch from 
151.101.114.49 started
debug: SSL connection to *.abuse.ch authenticated ip4 151.101.114.49 port 443 
(len 16)
debug: auth zone abuse_ch_threatfox. transfer failed, wait
debug: auth zone abuse_ch_threatfox. timeout in 48 seconds


This bug is fixed in upstream and should be fairly easy to backport:
