pkgin doesn't work with https and proxy

Hi,

I installed pkgin via pkg_add on NetBSD 10.0, but it doesn't work
with https and proxy.

pkgin update failed with the following error:

  netbsd10# pkgin update

It works with http:

  netbsd10# pkgin update

ftp(1) command can fetch pkg_summary.gz under the same environment:

  netbsd10# ftp

The version of pkgin:

  netbsd10# pkgin -v
  pkgin 23.8.1 (using SQLite 3.26.0)

Is this a known issue?
Any ideas?

Thanks,
