How to Fix Alamofire AFError Code 3 on iPhone and iPad
Question details
The user is encountering an Alamofire AFError Code 3 when running an application on an iPhone or iPad, preventing successful network connections.

- Product
- Alamofire (iOS Application)
- Device & OS
- iOS / iPadOS
- Scenario
- Using an iOS application that relies on the Alamofire networking framework to communicate with web servers.
- Observed behavior
- The application fails to connect or load data, displaying an Alamofire AFError Code 3 instead of completing the network request.
Ensure your iOS device has an active and stable internet connection, as Alamofire errors are frequently tied to network connectivity interruptions or server timeouts.
Contact the App Developer or Alamofire Support
Since Alamofire is a third-party Swift networking library, the application developer is best equipped to diagnose underlying code errors.
Microsoft 365 support forums are unable to troubleshoot third-party iOS software like Alamofire. Getting in touch with the app's creator is the most direct path to a resolution.
Take note of which specific app was open when the Alamofire AFError Code 3 appeared on your screen.
Open the App Store on your iPhone or iPad, search for the app, scroll down to the 'Ratings & Reviews' or 'Information' section, and tap 'App Support'.
Send a detailed message to the developer describing the AFError Code 3, what you were doing when it occurred, and your iOS version.

Perform Basic iOS Network Troubleshooting
AFError Code 3 often indicates an unacceptable status code or networking failure. Resetting your connection can sometimes resolve temporary glitches.
Try WPS Office for Seamless iOS Productivity
While troubleshooting third-party iOS networking issues like Alamofire errors, you may still need reliable tools for document management. WPS Office is a lightweight, free alternative to Microsoft Office that works flawlessly on iOS devices without complex networking dependencies.
- 1. Open the App Store: Unlock your iPhone or iPad and tap the App Store icon.
- 2. Search for WPS Office: Type 'WPS Office' into the search bar and select the official application from the results.
- 3. Download and install: Tap 'Get' to download the app and easily manage your Word, Excel, and PowerPoint files for free.

Frequently Asked Questions
What is Alamofire AFError Code 3?
AFError Code 3 usually indicates an 'unacceptable status code' response from the server during a networking request made by the Alamofire framework in an iOS app. It means the server returned an error (like a 404 or 500) that the app's code did not expect.
Can Microsoft 365 support help with Alamofire errors?
No, Microsoft 365 support typically cannot troubleshoot Alamofire errors on iOS. Alamofire is a third-party open-source networking library entirely separate from Microsoft's ecosystem.
Does reinstalling the app fix AFError Code 3?
Sometimes. Deleting the app and reinstalling it from the App Store can clear corrupted cache files or outdated configurations that might be causing the server requests to fail.
Is Alamofire a virus or malware?
No. Alamofire is a widely used, legitimate open-source HTTP networking library for macOS and iOS. It is safely used by thousands of reputable developers to manage web requests.
