How To Troubleshoot the “Error Occurred While Checking for a Software Update” Issue

Running into that annoying “An error occurred while checking for a software update“ message on the iPhone after trying to update can be pretty frustrating. Usually, it’s a network hiccup or storage issue, but sometimes it’s something a little more specific. The key is to troubleshoot step by step, so you know what to try next when one fix doesn’t do the trick. This guide is about covering the usual suspects – from server overloads to network settings – and hopefully, getting that update finally installed. Because of course, iOS updates are critical for security patches and new features, so delaying isn’t ideal. Just keep in mind, occasionally, these errors pop up temporarily if Apple’s servers are busy or offline. So, patience along with troubleshooting helps a lot.

How to Fix the “Error While Checking for an Update” on iPhone

Check Apple Server Status

Sometimes Apple’s servers are just overloaded or down for maintenance, which messes with your ability to download updates. Honestly, it’s kind of weird how often this can happen, especially right after a new iOS drops. Before messing around with settings, hit up Apple’s System Status page. If the update servers or related services are marked as unavailable, all you can do is wait a few hours. Usually, they fix this pretty quick, but on some launches, the queues are crazy long, and it can take half a day. Sometimes, on a busy network, the servers strain a little more, and you get a timeout. Expect the status indicator to turn green if everything is back online. If not, just circle back later. No point in trying repeatedly during a known outage.

Spend a few minutes checking your network connection

This might be obvious, but a weak or unstable Wi-Fi connection can cause the update check to fail. If you’re connected to some sketchy Wi-Fi or your signal drops mid-download, you’ll likely see that error. Make sure you’re connected to a solid, high-speed network. Better yet, switch to a different Wi-Fi network if possible or restart your router. On some setups, your Wi-Fi might be connected, but the internet isn’t really working properly—try opening a webpage or streaming a video to test it. Also, disconnect any VPNs or proxies temporarily; they sometimes interfere. Keep the phone plugged in and connected to Wi-Fi during the whole process. It sounds dumb, but I’ve seen this issue clear up just because the Wi-Fi was flaky.

Reset Network Settings – a kinda brutal but effective move

If your connection seems fine but you still get the error, resetting network settings can do the trick. It’s a bit invasive, but it clears out any weird network configs that might be causing issues. For that, go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. When asked, confirm and wait for the reset to finish. Your Wi-Fi passwords, VPN configs, and Bluetooth pairings will be erased, so have those handy if needed to reconnect. After that, reconnect to Wi-Fi and try the update again. In some cases, this just kicks the network into a cleaner state.

Make sure there’s enough storage on your iPhone

This is a common one that trips a lot of people up. The update needs some free space to install properly. If your storage is almost full, the update won’t even start or will throw errors. Head over to Settings > General > iPhone Storage. Check what’s taking up space—big videos, photos, apps—and delete or offload some of those files. Alternatively, upload photos and videos to iCloud or transfer stuff to your PC or external drive. You might be surprised how much space gets freed up. The update will be way more likely to go through if you’ve got at least a couple of gigabytes free.

Set Date & Time to Automatic

If your device’s clock is way off, some updates might refuse to check or install. Head to Settings > General > Date & Time and toggle Set Automatically on. This helps ensure your device’s clock is synchronized with Apple’s servers and isn’t causing weird errors. On some machines, this fix also helps with certificate validation issues that throw the update errors. Not sure why it works, but I’ve seen cases where the date being wrong, even off by a few minutes, caused a check failure.

Try updating via iTunes or Finder

When the over-the-air method refuses to work, connecting through iTunes (Windows or older Mac) or Finder (macOS Catalina and later) can often do the trick. Plug your iPhone into your computer, open iTunes or Finder, and see if it detects your device. On iTunes, click the device icon near the top, then look for the Update button. If it prompts you to download and install the latest iOS, go ahead. If not, you can manually check for updates inside iTunes. Sometimes, this method bypasses whatever’s stopping the OTA update from working. Just be sure your PC or Mac is connected via a stable Ethernet or Wi-Fi connection—and note, this might still give issues if your PC isn’t properly synced or if iTunes isn’t up to date.

Contact Apple Support if all else fails

If nothing’s helping, and the error persists even after trying all these, it might be time to get official support involved. You can visit Apple’s support page and explain your issue. They might have specific diagnostics or patches for your case. Sometimes, the error kind of hints at deeper problems—like a faulty baseband chip or a corrupted update cache. Just be prepared, they might suggest a hardware check if software fixes don’t work.

Summary

• Check Apple’s system status page for outages.
• Ensure your Wi-Fi connection is stable and strong.
• Reset network settings if needed.
• Free up storage on the device.
• Set date & time automatically.
• Try updating through iTunes or Finder.
• Contact Apple support if stuck.

Wrap-up

Getting past this error is often just a matter of confirming your network is solid, your storage isn’t full, and Apple’s servers are up. None of these fixes are super complicated, but they do require some patience and trying a few things in order. On one setup it worked after resetting network settings, on another, freeing space did the trick. Usually, it’s something simple but sneaky causing the hiccup. Fingers crossed this gets one update moving — hope it works for you.
