原文 2020-03-03 09:20:54 0 2 ios/ angular/ ionic-framework

the iphone can connect to the testing server, however, with local.network providing the IP address 192.168.x.xx:3000 cannot connect with the error Failed to load resource: A server with the specified hostname could not be found. iphone 可以连接到测试服务器，但是，local.network 提供 IP 地址 192.168.x.xx:3000 无法连接，错误Failed to load resource: A server with the specified hostname could not be found. There is no problem with an Android device connecting but with iOS I receive the error above.连接 Android 设备没有问题，但使用 iOS 我收到上述错误。

Also, I have changed the DNS manually to what is suggested in other posts to 8.8.8.8 however the issue still remains the same.此外，我已将 DNS 手动更改为其他帖子中建议的8.8.8.8 ，但问题仍然存在。 thanks.谢谢。

this has something to with on which band you're connected to your wifi.这与您连接到 wifi 的频段有关。 You can resolve this by connecting to the 2.4Ghz band and not the 5Ghz.您可以通过连接到 2.4Ghz 频段而不是 5Ghz 来解决此问题。 I still don't know why but it only happens with iOS devices.我仍然不知道为什么，但它只发生在 iOS 设备上。 MacOS is all fine. MacOS 一切正常。
