How to Fix AltStore Error 22410 When Installing Apps

AltStore has become one of the most popular tools for installing unofficial apps and emulators on iPhone and iPad without jailbreaking. It works by sideloading apps using your Apple ID and syncing through AltServer on your computer. While the process usually works smoothly, many users run into issues during installation.

One of the most common problems reported by iOS users is AltStore Error 22410. This error typically appears when trying to install or refresh apps through AltStore, and it can prevent sideloading from completing successfully.

If you are seeing altstore error 22410, do not worry. The issue is usually related to connection problems between AltStore, AltServer, and your Apple device. In most cases, it can be fixed with a few simple adjustments.

This detailed guide explains why altstore error 22410 happens and provides proven solutions that work in 2026 for both Windows and macOS users.

What Is AltStore Error 22410?

AltStore Error 22410 is a communication error that occurs when AltStore on your iPhone cannot properly connect with AltServer running on your computer.

AltStore relies on AltServer to sign and install apps using your Apple ID. When this connection fails or becomes unstable, the installation process stops and the error message appears.

In simple terms, the problem usually means:

• AltStore cannot reach AltServer
• WiFi syncing between the device and computer is not active
• Apple services required for sideloading are not running
• Firewall or antivirus software is blocking the connection

Understanding the root cause helps fix altstore error 22410 quickly without reinstalling everything.

Common Causes of AltStore Error 22410

Before jumping into solutions, it helps to know why this error appears in the first place.

1. AltServer Not Running

If AltServer is closed or crashed on your computer, AltStore cannot communicate with it. Since AltServer signs apps, the installation process fails and produces altstore error 22410.

2. iPhone and Computer on Different Networks

AltStore requires your iPhone and computer to be on the same WiFi network. If your phone switches networks or mobile data takes priority, the connection breaks.

3. Mail Plugin Not Enabled (macOS)

On macOS, AltServer uses a Mail plugin to sign apps. If the plugin is disabled, sideloading fails and the system may display altstore error 22410.

4. Firewall or Antivirus Blocking AltServer

Security software may block AltServer from communicating with your iPhone.

This is especially common on Windows systems using aggressive antivirus programs.

5. Expired Apple ID Session

AltStore uses your Apple ID to sign apps. If the login session expires or becomes invalid, AltStore may fail to install apps properly.

How to Fix AltStore Error 22410

The following solutions are the most effective ways to fix altstore error 22410. Work through them in order until the issue is resolved.

1. Restart AltServer

The simplest solution is often the most effective. Restarting AltServer resets the connection between your computer and iPhone.

Steps:

• Close AltServer completely
• Reopen AltServer from your Applications or System Tray
• Reconnect your iPhone
• Try installing the app again through AltStore

This refreshes the signing connection and often fixes altstore error 22410 instantly.

2. Ensure iPhone and Computer Are on the Same WiFi

AltStore depends on local network communication between your iPhone and AltServer.

If the devices are on different networks, the installation request cannot reach the computer.

Check this:

• Open WiFi settings on your iPhone
• Confirm it is connected to the same router as your computer
• Disable mobile data temporarily
• Retry installing the app

This is one of the most common fixes for altstore error 22410.

3. Enable WiFi Sync in iTunes or Finder

AltStore requires WiFi syncing to communicate with AltServer.

If this option is disabled, AltStore cannot send installation requests.

On Windows:

• Open iTunes
• Connect your iPhone with a cable
• Select your device
• Enable Sync with this iPhone over WiFi
• Apply changes

On macOS:

• Open Finder
• Select your iPhone
• Enable WiFi syncing

After enabling it, retry the sideloading process to resolve altstore error 22410.

4. Reinstall AltStore on Your iPhone

If the AltStore installation on your device becomes corrupted, it may cause signing errors.

Reinstalling AltStore often resolves these problems.

Steps:

• Delete AltStore from your iPhone
• Open AltServer on your computer
• Select Install AltStore
• Choose your iPhone
• Install it again

Once installed again, the altstore error 22410 usually disappears.

5. Re-login to Your Apple ID

Apple ID authentication is required to sign sideloaded apps.

If the session expires, AltStore may fail to install apps.

Fix it by:

• Opening AltServer
• Choosing Install AltStore again
• Entering your Apple ID credentials
• Reinstalling AltStore

This refreshes the signing certificate and resolves altstore error 22410 in many cases.

6. Allow AltServer Through Firewall

Windows Defender or other antivirus software may block AltServer.

When this happens, AltStore cannot communicate with the computer.

Fix:

Once AltServer is allowed, the connection should work normally.

Steps:

• Restart your iPhone
• Restart your computer
• Open AltServer again
• Retry installation

Older versions of AltStore may contain bugs that cause installation errors.

Developers frequently release updates to improve compatibility with new iOS versions.

To update:

• Download the latest AltServer version
• Install it on your computer
• Update AltStore on your iPhone

This ensures compatibility with the latest iOS releases and prevents altstore error 22410.
