每次在Mac上进行(Mac)FaceTime通话时，您是否都会收到“通话失败”错误？提示“为什么我的FaceTime通话总是失败？” 来自SwitchingToMac读者的问题，我们重点介绍了(SwitchingToMac)FaceTime通话失败的九 (9) 个可能的解决方案。
由于各种原因，您会收到此错误，包括互联网连接不良、临时系统故障、过时或漏洞百出的 macOS 版本、不正确的日期和时间设置、FaceTime服务器停机时间等等。尝试以下故障排除解决方案，看看哪一个最适合您。
检查互联网连接
您需要快速且活跃的互联网连接才能享受最佳的FaceTime体验。如果您的Mac上的(Mac)FaceTime通话一直失败，请通过在任何浏览器上访问网页来测试您的网络连接。如果您无法访问网页，请关闭Mac的Wi-Fi，重新打开，然后重新加入网络。
如果问题仍然存在，请将您的Mac连接到另一个Wi-Fi（或以太网(Ethernet)）网络，然后重试。您还应该考虑暂停任何正在进行的下载，因为这可能会减少可用带宽并减慢您的互联网连接速度。阅读有关获得更快互联网的综合指南，(this comprehensive guide on getting faster internet)了解更多故障排除提示。
禁用 VPN
除了减慢您的互联网连接速度外，VPN 还会干扰 FaceTime 通话(VPNs can also interfere with FaceTime calls)。打开您的VPN设置并确保连接未路由到无法使用 FaceTime 的国家(country where FaceTime isn’t available)/地区。更好(Better)的是，禁用您的VPN连接并检查您是否能够毫无问题 地拨打和接听FaceTime电话。(FaceTime)
强制退出 FaceTime
(FaceTime)如果FaceTime应用程序出现故障， (FaceTime)FaceTime通话也可能会失败。强制(Force)停止应用程序并重试。

重新打开 FaceTime(Reopen FaceTime)并检查是否修复了“通话失败”错误。
检查 FaceTime 服务器状态
有时问题源于苹果的终结。如果为服务提供动力的服务器出现故障或不可用、无响应或正在经历停机（可能是由于日常维护）， FaceTime(FaceTime)将出现各种错误。
前往Apple System Status 页面并检查(Apple System Status page)FaceTime旁边的颜色代码。绿色(Green)表示FaceTime运行正常，黄色(Yellow)表示服务存在问题，而红色(Red)表示中断。
如果FaceTime 的服务器出现问题，您能做的最好（也是唯一）的事情就是等到Apple解决问题。
调整日期和时间设置
不正确的日期和时间配置也会中断FaceTime操作。确保将 Mac 的日期和时区设置配置为自动更新。
- 通过单击菜单栏左上角的 Apple标志( logo)启动系统偏好设置。(System Preferences )

- 或者，启动FaceTime ，在菜单栏上选择FaceTime ，选择(FaceTime)Preferences，取消选中Enable this account。
- 等待(Wait)大约 5-10 秒，然后再次选中启用此帐户(Enable this account)选项。
重新启动你的 Mac
重新启动Mac可以修复导致(Mac)FaceTime通话不断失败的临时系统故障。单击菜单栏左上角的Apple 标志，然后选择(Apple logo)重新启动(Restart)。如果Mac重新启动后问题仍然存在，请继续执行下一个故障排除解决方案。

FaceTime Calls Failing on Mac? 9 Fixes to Try
Dо yоu get a “Call Failed” error every time you makе FaceTime calls on your Mac? Prompted by a “Why do my FaceTime calls keep failing?” question from a SwitchingToMac reаder, we highlight nine (9) possible sоlutions to FaceTime call failureѕ.
You’ll get this error due to a variety of reasons ranging from poor internet connectivity to temporary system glitches, outdated or bug-ridden macOS version, incorrect date and time settings, FaceTime server downtime, and so on. Try the following troubleshooting solutions and see which one works the magic for you.
Check Internet Connection
You need a fast and active internet connection to enjoy the optimal FaceTime experience. If FaceTime calls keep failing on your Mac, test your network connection by visiting a webpage on any browser. If you can’t access webpages, turn off your Mac’s Wi-Fi, turn it back on, and rejoin the network.
If the problem persists, connect your Mac to another Wi-Fi (or Ethernet) network and try again. You should also consider pausing any ongoing download(s) as that could reduce available bandwidth and slow down your internet connection. Read this comprehensive guide on getting faster internet for more troubleshooting tips.
Disable VPN
In addition to slowing down your internet connection, VPNs can also interfere with FaceTime calls. Open your VPN settings and ensure the connection isn’t routed to a country where FaceTime isn’t available. Better yet, disable your VPN connection and check if you’re able to make and receive FaceTime calls without issues.
Force Quit FaceTime
FaceTime calls may also fail if the FaceTime app is malfunctioning. Force stop the app and try again.
- Press Command + Space, type activity monitor in the Spotlight Search, and press Return to launch the Activity Monitor.
- Select FaceTime and click the Stop (x) icon on the Activity Monitor’s toolbar.
- Select Force Quit on the prompt to force close FaceTime.
Reopen FaceTime and check if that fixes the “Call Failed” error.
Check FaceTime Server Status
There are times when the problem stems from Apple’s end. FaceTime will present all sorts of errors if the servers powering the service are down or unavailable, unresponsive, or are experiencing downtime—perhaps due to routine maintenance.
Head to the Apple System Status page and check the color code next to FaceTime. Green means FaceTime is operating correctly, Yellow denotes issues with the service, while Red indicates an outage.
If there’s an issue with FaceTime’s servers, the best (and only) thing you can do is to wait until Apple fixes the problem.
Adjust Date and Time Settings
Incorrect date and time configurations can also disrupt FaceTime operations. Ensure your Mac’s date and time zone settings are configured to update automatically.
- Launch System Preferences by clicking the Apple logo at the top-left corner of the menu bar.
- Select Date & Time, and click the lock icon at the bottom left corner.
- Enter your Mac’s password or authenticate using Touch ID to edit the Date & Time preferences.
- In the Date & Time tab, make sure the “Set date and time automatically” option is checked.
- In the Time Zone tab, check the option that reads “Set time zone automatically using current location.”
Re-Enable FaceTime
Another way to fix FaceTime call failures is by turning off and re-enabling the service. There are several ways to disable FaceTime on Mac.
- The first and easiest method is to launch FaceTime, select FaceTime on the menu bar, and select Turn FaceTime Off.
- Wait for some seconds and select Turn FaceTime On to re-enable the service.
- Alternatively, launch FaceTime, select FaceTime on the menu bar, select Preferences, uncheck Enable this account.
- Wait for about 5-10 seconds and check the Enable this account option again.
Restart Your Mac
Restarting your Mac could fix temporary system glitches causing FaceTime calls to keep failing. Click the Apple logo at the top-left corner of the menu bar and select Restart. Proceed to the next troubleshooting solution if the problem continues when your Mac comes back on.
Sign Out of FaceTime (Reactivate FaceTime)
If the “Call Failed” error continues after trying the fixes mentioned above, disconnect your Apple ID from FaceTime, and sign back in.
- Open FaceTime, select FaceTime on the menu bar, select Preferences, and click the Sign Out button next to your Apple ID address.
- Select Sign Out on the confirmation prompt to sign out of FaceTime.
- Enter your Apple ID email and password in the provided dialog boxes and select Next to sign in.
That’ll reactivate FaceTime on your Mac and hopefully fix the call failure issue. If you’re having difficulties reactivating FaceTime, refer to this article on fixing FaceTime activation issues.
Update macOS
Sometimes, new macOS releases harbor software bugs that cause FaceTime calls to keep failing. If the issue begins after installing a new update, you can either wait until Apple fixes the bug or downgrade your Mac to a stable, bug-free macOS version.
Outdated macOS versions can also result in call failures. If you haven’t updated your Mac in a very long time, head to System Preferences > Software Updates and install any update available on the page.
Last Resort: Contact Apple Support
We’re confident that at least one of these fixes should resolve the FaceTime call failure issue. If not, contact Apple Support for assistance or visit a nearby Apple Genius bar to have your Mac examined.
