Failed to initialize monitor Thread: Unable to establish loopback connection
提问by Kees Koenen
Since yesterday suddenly my Eclipse does not work anymore. The error is "Failed to initialize monitor Thread: Unable to establishe loopback connection". I googled and tried the following:
从昨天开始，我的 Eclipse 突然不再工作了。错误是“初始化监视器线程失败：无法建立环回连接”。我用谷歌搜索并尝试了以下内容：
- IPv6 completely off, if I ping localhost I get back 127.0.0.1
- Firewall exceptions added for eclipse.exe and adb.exe
- Adb killed and re-started
- Reset Adb from eclipse
- Virus scanners off (temporarily)
- IPv6 完全关闭，如果我 ping 本地主机，我会返回 127.0.0.1
- 为 eclipse.exe 和 adb.exe 添加了防火墙例外
- Adb 被杀死并重新启动
- 从 Eclipse 重置 Adb
- 病毒扫描程序关闭（暂时）
Nothing seems to help, I'm lost. Besides, if I try to update I get the error message also:
似乎没有任何帮助，我迷路了。此外，如果我尝试更新，我也会收到错误消息：
Some sites could not be found. See the error log for more detail. Unable to read repository at http://dl-ssl.google.com/android/eclipse/content.xml. Permission denied: connect
无法找到某些站点。有关更多详细信息，请参阅错误日志。无法在http://dl-ssl.google.com/android/eclipse/content.xml读取存储库。权限被拒绝：连接
.. I can browse from Eclipse (with the Internal Web Browser perspective), so there is an internet connection. Furthermore, no proxies, just a direct connection.
.. 我可以从 Eclipse 浏览（使用内部 Web 浏览器透视图），所以有互联网连接。此外，没有代理，只是直接连接。

Solution : turn off Teredo Tunneling Pseudo-Interface.
解决方案：关闭 Teredo Tunneling Pseudo-Interface。
This probably converts IP4 to IPv6 addresses or something, resulting in an IPv6 address for your localhost (strange though, that a PING still results in IP4). Anyway, turning it off (Device manager > View > Show hidden devices > right click on Teredo > disable) solves the problem!
这可能会将 IP4 转换为 IPv6 地址或其他地址，从而为您的 localhost 生成 IPv6 地址（但很奇怪，PING 仍会生成 IP4）。无论如何，将其关闭（设备管理器 > 查看 > 显示隐藏设备 > 右键单击 Teredo > 禁用）可以解决问题！
I found out by doing a ipconfig /all in the NON working situation. It showed :

My solution was: Terminate my proxifier.exe
我的解决方案是：终止我的 proxifier.exe
I guess eclipse doesn't like proxies
我猜 eclipse 不喜欢代理

Please check your anti virus blocked your eclipse,just give allow full access to eclipse on your antivirus security settings.
请检查您的防病毒是否阻止了您的 eclipse，只需在您的防病毒安全设置中授予对 eclipse 的完全访问权限。

I suspect you are using Java 7 which looks like it prefers IPV6 over IPV4.
So you need to make sure that -Djava.net.preferIPv4Stack=trueis a jvm argument.
我怀疑您使用的是 Java 7，它看起来更喜欢 IPV6 而不是 IPV4。所以你需要确保这-Djava.net.preferIPv4Stack=true是一个 jvm 参数。

I got this problem after updating ADT and SDKs etc. I did solutions above but didn't work at all. So, update JDK from "JDK 8u25" to "JDK 8u45" and changed path setting (on Windows and Eclipse). This works for me perfectly!
我在更新 ADT 和 SDK 等后遇到了这个问题。我做了上面的解决方案，但根本不起作用。因此，将 JDK 从“JDK 8u25”更新为“JDK 8u45”并更改路径设置（在 Windows 和 Eclipse 上）。这对我来说完美无缺！

I came here to add that in my case the solution that worked was to change eclipse.ini. I did try ALL the other answers in this thread and in other threads (reinstalling Eclipse, reinstalling the Android SDK, reinstalling Java 7 as well, rebooting, checking if Toledo was installed, etc). After an exhaustive google search, I came across this:
我来这里补充一点，就我而言，有效的解决方案是更改 eclipse.ini。我确实尝试了该线程和其他线程中的所有其他答案（重新安装 Eclipse、重新安装 Android SDK、重新安装 Java 7、重新启动、检查是否安装了 Toledo 等）。经过详尽的谷歌搜索，我发现了这个：

However, I am not knowledgeable enough to understand why it worked. If anyone has any idea, please let me know. Thanks
但是，我的知识不足，无法理解它为什么起作用。如果有人有任何想法，请告诉我。谢谢
