It can be verified that the magnet is :

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

This page says, you need to enable DHT option while downloading using magnet-links:-

This official documentation page says, it is enabled by default from version 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

Checked the release notes from GitHub, couldn't find the exact release since the flag --enable-dht has been made to true.

Upgrade to the latest version to have the flag enabled by default (or) enable it explicitly if you are using an older version.

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"
