我无法从运行Windows 10的笔记本电脑访问一个特定的健康相关网站。我在chrome中收到的错误是：
This site can’t be reached
The webpage at http://www.apneaboard.com/forums/ might be temporarily down or it may have moved permanently to a new web address.
ERR_NAME_RESOLUTION_FAILED
我试图通过3种不同的浏览器访问该站点，但没有成功。有趣的是，可以通过其他设备访问该网站，例如电话和同一网络上的标签页。如果我使用VPN并通过其他国家/地区连接，也可以在同一台笔记本电脑上访问网站。该网站未被禁止-在伴侣的计算机上可以本地访问，并且可以在网吧中浏览。
我的ISP可以通过NBN连接提供互联网，因为它可以为澳大利亚的数百万人提供互联网，并且我的路由器没有任何限制。
我该怎么做才能解决此问题？
编辑：根据消息和答案，我正在更新以下内容：1）ipconfig / flushdns对这个问题没有影响。该网站仍然无法访问2）以下是该网站的nslookup结果。首先不使用VPN，其次使用VPN
C:\>nslookup apneaboard.com

3）在vpn上打开或关闭网站会显示以下消息：
Ping request could not find host www.apneaboard.com. Please check the name and try again.
4）为我的wifi连接设置的DNS已经是google dns：IPv4设置
选择自动获取IP地址。首选DNS服务器是8.8.8.8，备用DNS服务器是8.8.4.4
这继续困扰着我。该网站仍然可以通过vpn而不是通过我的常规连接访问。还有其他故障排除步骤吗？
编辑2：我的主机文件中绝对没有任何内容。所有行都被注释掉了，我尝试使用该站点的IP地址（我是通过vpn通过ping获得的- 在连接到vpn 时访问http：// IP时，我看到的页面与该页面相同（很抱歉-如果您是该网站的所有者，请联系您的主机提供商-页面）我尝试禁用IPV6，但没有运气。当禁用ipv6时，它仍然可以通过vpn起作用。我还下载并使用了Microsoft解决方案来仅禁用ipv6可以肯定的是，除了从n / w属性中取消选中它之外，以下是nslookup -d2输出：

尝试使用和不使用VPN都在地址上进行nslookup。

在完成MikaelKjaer的建议之后，尝试将通过VPN获得的IP地址加载到浏览器中，但不在 VPN 外部。

尝试使用Google的DNS，而不是ISP的DNS。遵循howtogeek指示，仅更改DNS并将“获取IP”保留为“自动”。（使用相同的DNS数字（8.8.8.8＆8.8.4.4） howtogeek.com/howto/19249/...

那你的/ etc / HOSTS文件呢？是否阻止了该特定站点？

禁用IPv6后，您能看到什么吗？看来您的计算机正在使用IPv6分辨率并且出现故障。我的猜测是您的其他设备正在使用IPv4访问该站点（并且您的VPN仅配置了IPv4）。
