Gradle sync failed: Cause: dl.google.com:443 failed to respond

太久沒開啟Android Studio,開啟更新同步Gradle
竟然提示

	Gradle sync failed: Cause: dl.google.com:443 failed to respond

呵呵o(￣︶￣)o，優雅地開啟VtwoRAY
結果還是

	Gradle sync failed: Cause: dl.google.com:443 failed to respond

(O_o)??

查了下原來要註釋一下gradle.properties裡的https代理設定（注意是Global Properties）

systemProp.http.proxyHost=127.0.0.1
systemProp.http.proxyPort=10808
#systemProp.https.proxyHost=127.0.0.1
#systemProp.https.proxyPort=10808
