試したこと

Connectionエラーになっているのでプロキシが原因かなとおもい、検索して出てきた設定の仕方に従って、sbtconfig.txtに追加してみましたが(実行時に一応読み込まれてる？L.9-12)何も変化ありませんでした。

この原因と解決方法がわかる方がいましたら教えてください。

環境

OS:Windows10
Java:jdk1.8.0_241
sbt:1.3.10

補足

sbtは公式から最新verをインストーラを使って(デフォルトのまま)インストールしました。

Answer 1

sbt 起動時の引数や、設定に -Dhttps.protocols=TLSv1.2 を追加して起動してはどうでしょうか。
（その場合、ブラウザやOSの設定でプロキシーサーバーの設定をしていない場合、Proxy 周りの設定は不要かもしれません）

以下の質問と同じ回答になるかと思いますが、
maven の接続先のTLSバージョンのサポート切れの影響かと思われます。
