502从Artifactory下载Gradle Wrapper时出错

我很难让Gradle包装器从Artifactory实例下载-bin.zip文件。我想通过我们的Artifactory工件管理器分发我的公司修改(添加的init脚本)版本的Gradle,但收到了来自Artifactory服务器的502错误。不幸的是,Artifactory服务器的日志中没有任何用于此请求的有用内容。我已经验证了我的浏览器可以成功并完全下载该文件 http://testlab3:8081/artifactory/simple/ext-release-local/gradle/gradle/1.4/gradle-1.4-bin.zip 如果我把它输入到位置栏中。

以下是相关的结束语:

task wrapper(type: Wrapper) {
    distributionUrl = 'http://testlab3:8081/artifactory/simple/ext-release-local/gradle/gradle/1.4/gradle-1.4-bin.zip'
}  

然后我执行

$gradle wrapper

以下是我尝试使用包装器时得到的跟踪:

有人有什么建议吗?
