This pagesays, you need to enable DHT option while downloading using magnet-links:-
这page表示，您需要在使用磁力链接下载时启用 DHT 选项：-
This official documentationpage says, it is enabled by default from version 1.25.0
这个official documentation页面说，它从版本默认启用1.25.0
--enable-dht[=true|false] Enable IPv4 DHT functionality. It also enables UDP tracker support. If a private flag is set in a torrent, aria2 doesn't use DHT for that download even if true is given. Default: true
--enable-dht[=true|false] 启用 IPv4 DHT 功能。它还启用 UDP 跟踪器支持。如果在 torrent 中设置了私有标志，即使给出了 true，aria2 也不会为该下载使用 DHT。默认值：真
Checked the release notes from GitHub, couldn't find the exact release since the flag --enable-dhthas been made to true.
从 中查看发行说明GitHub，找不到确切的发行版，因为标志--enable-dht已更改为true。
Upgrade to the latest version to have the flag enabled by default (or) enable it explicitly if you are using an older version.
升级到最新版本以默认启用该标志（或）如果您使用的是旧版本，则明确启用它。
aria2c --enable-dht=true "magnet:?xt=urn:btih:2D2CAE6AC83800490327547053597BAFF6701C2F&dn=battlestar+galactica+season+1+s01+1080p+bluray+x265+hevc+aac+5+1+joy+utr&tr=udp%3A%2F%2Ftracker.publicbt.com%2Fannounce&tr=udp%3A%2F%2Fglotorrents.pw%3A6969%2Fannounce&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&tr=udp%3A%2F%2Ftracker.opentrackr.org%3A1337%2Fannounce"
