Aircall relies on accurate system time to establish secure, real-time connections. If the clock on your computer is out of sync by more than 1.5 seconds, the Aircall Workspace app may disconnect, fail to register, or stop receiving calls. This guide explains how to fix clock sync issues on both Windows 11 and macOS.

Important: If your device clock is not synchronized with the operating system's official time servers, Aircall's connection may be rejected for security reasons. Fixing your device time usually resolves disconnections immediately.

Why time synchronization is critical

Aircall uses WebSockets and secure tokens to maintain real-time communication. These rely on accurate timestamps. If your device clock drifts too far from Aircall's servers, you may experience:

  • Inability to receive or place calls
  • Intermittent disconnections
  • The Aircall app failing to load
  • Missing real-time updates: when a contact is updated by a teammate, or when a conversation is closed for example

Keeping your device clock synced prevents these issues.

Fix device clock sync on Windows 11

Follow these steps to resynchronize your Windows 11 device clock.

Steps

  1. Open the Settings on your computer and go to Time & language > Date & time.
  2. Make sure both Set time automatically and Set time zone automatically are turned ON.
  3. Scroll to Additional settings and click Sync now to force a manual synchronization.
    • A green checkmark should confirm success with the Windows time server.
  4. Quit Aircall completely via the system tray.
  5. Restart your computer to allow Windows to recalibrate system services.
  6. Relaunch Aircall and confirm that the connection is now stable.

Fix device clock sync on macOS

macOS must sync with Apple's time servers to ensure a correct timestamp.

Steps

  1. Open the Apple menu > System Settings (or System Preferences).
  2. Go to General > Date & Time.
  3. Turn Set time and date automatically ON.
  4. If it is already enabled, toggle it OFF, then ON again to force a fresh sync.
  5. Confirm that the time server is set to time.apple.com.
  6. Fully quit Aircall and restart your Mac so the system kernel and services apply the new time.

Troubleshooting

If issues continue after syncing your clock:

Tip: Restarting the computer is mandatory on both Windows and macOS. This ensures system-level time recalibration and is often the key step that resolves the issue.

Additional checks

  • Ensure your VPN is disabled, as it may interfere with time servers.
  • Confirm your company firewall allows access to the system time servers:
    • Windows: time.windows.com
    • macOS: time.apple.com
  • Make sure your device is connected to a stable network during synchronization.
  • If the sync button shows an error, try again after connecting to a different network.
