我正在尝试从Eclipse Neon 64位打开Eclipse Marketplace。每当我尝试选择帮助 - > Eclipse Marketplace，我收到以下消息：
Cannot open Eclipse Marketplace
Cannot install remote marketplace locations: Connection failed
在错误日志中：
org.eclipse.core.runtime.CoreException: Cannot install remote marketplace locations: Connection failed
This is most often caused by a problem with your internet connection. Please check your internet connection and retry.
