问项目刷新失败，错误:连接超时: conect

我已经在设置->HTTP代理->自动检测代理设置中进行了更改，但不起作用。在我将我的android工作室升级到2.3.3之后，我遇到了这个问题。 我已经检查过旧版本的android工作室，但现在它不起作用了。

清除分级任务时的：-

下面是由: org.gradle.internal.resource.transport.http.HttpRequestException:引起的同步错误：-无法获得“https://jcenter.bintray.com/com/google/gms/google-services/3.0.0/google-services-3.0.0.pom”后的日志。在org.gradle.internal.resource.transport.http.HttpClientHelper.performRequest(HttpClientHelper.java:82)由: java.net.ConnectException:连接超时:连接在org.apache.http.conn.ssl.SSLConnectionSocketFactory.connectSocket(SSLConnectionSocketFactory.java:337) at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:134) .147-06-20 15:57:53,574 1049961警告- nal.AbstractExternalSystemTask -连接超时:连接com.intellij.openapi。com.android.tools.idea.gradle.project.sync.idea.ProjectImportErrorHandler.getUserFriendlyError(ProjectImportErrorHandler.java:86)：连接超时:在externalSystem.model.ExternalSystemException上连接
