cached-directory update always failure via proxy



Hello TOR developers,

There is a problem existing long time that the cached-directory
almostly can not be updated via parent fascist proxy.

The detail:
Environment:LAN, fascist http/https proxy, remote port only 80, 443 allowed.

When using tor.exe -httpsproxy 127.0.0.1:8888 -fascistfirewall 1
-firewallports 443, see following:

And I find something in the firewall monitor that TOR not only connect
proxy but also try to directly connect to some remote servers' IP port
9001/9030 although parent proxy is declared. But very very few times,
when using tor.exe -httpproxy 127.0.0.1:8888 -fascistfirewall 1
-firewallports 80, TOR can successfully download the latest
cached-directory.

Can you give some explanations or it's a real problem of proxy support?

Best regards,
