How to Fix: Google Detected Unusual Traffic on Safari iPhone?

Google throws the “Detected Unusual Traffic” error when it detects multiple server hits with the same IP addresses or compromised browser integrity. Avoiding free VPN service, resetting the network settings, restarting the phone solves the problem.

If you are sending quite many requests for data exchange from a particular device, then Google might identify that device as a robot or an automated bot.

The Silicon Valley Giants will recognize that many requests are continuously being sent from a single IP (mainly when using free or cheap VPN), which is against how a user would typically access a particular site.

As and when that happens, Google will send you a message that it has “detected unusual traffic” from your device. It will ask you to solve a captcha to verify that you are a human. Once you do so, you would be easily able to access that site. Unfortunately, things don’t seem relatively simple in the Apple ecosystem.

Our system has detected unusual traffic error in Safari iPhone

There have been numerous complaints from iPhone users that they are constantly getting bugged with the “detected unusual traffic” message. But the thing is, these users haven’t sent any abnormal amount of requests from their device.

Furthermore, even if they go ahead and solve the Captcha, it’s just a one-time relief. The next time they try and access the site, Captcha would re-appear. This is quite infuriating.

Fortunately, there does exist a few methods that are known to fix this issue. So without further ado, let’s check them out.

Restart iPhone

While it may sound like a simple fix, but trust us, a simple reboot of the device has been known to work out wonders when it comes to this error. Users were able to quickly fix this issue with just a single restart of their iPhone.

Here are the simple steps to reboot your iPhone:

  1. Press and hold the volume + power button to bring up the Power menu.
    iPhone Switch Off or Power Buttons combination
  2. Slide the Power Off slider to turn off the device.
  3. Now, press and hold the power button for a few seconds until you see the Apple logo apple logo.

The device to power on and then check if you can access the site without entering the captcha.

Close All Tabs | Restart Browser

If a lot of tabs are opened in your Safari browser, then each of them might ping Google at the same instance. As a result, Google might categorize it as invalid traffic and then show the error mentioned above.

Therefore, it is recommended that you close all the tabs, then restart the browser. Once that is done, see if the issue has been fixed or not.

While manually opening each of the closed tabs, later on, would call for some manual effort, it’s just a small price to pay if it rectifies this error.

Clear Safari Cookies

If the stored browser data gets corrupted, then it could result in quite a few issues. Likewise, it might even raise a false positive that the browser is constantly sending requests for data exchange.

This portrayal of the incorrect scenario could lead to quite a few issues, including the one we are currently dealing with. Therefore, the best way out is to delete these data and your browsing history right away.

Here are the steps to clear the cookies and website data from Safari on iPhone:

  1. Head over to the Settings app on your device.
  2. Choose the Safari app.
  3. Tap on the Clear History and Website Data command.

  4. Wait for the process to complete and then verify if the issue has been fixed or not.

Clearing cookies might sign you out of various sites; however, your stored information would remain secure. You would have to re-login to those sites.

Turn on HTTP/3

This issue is primarily imminent with the users who are using the carrier data rather than the WiFi. While Google has made a switch to the HTTP/3, few carriers are still to follow.

So to be on the same page, it is recommended that you manually carry out this switch.

Here are the steps to enable HTTP/3 compatibility in Safari iPhone:

  1. Launch the Settings app on your device.
  2. Choose the Safari app on the Settings page.
  3. Tap on Advanced and head over to the Experimental WebKit Features section.
  4. Now turn on the toggle next to HTTP/3.
    Toggle HTTP/3 in Safari Experimental WebKit
  5. Restart your browser and check if it gives out the desirable result.

This newer version of the Hypertext Transfer Protocol is much faster than its predecessor, but there is still some catching up left to do by many network providers.

Perform a Network Reset

In some instances, an incorrect network configuration might send unnecessary requests to a particular site. When that happens, Google is bound to send you the detected unusual traffic message on your Safari browser.

While manually identifying the network issue is indeed a tough job, what you could do is to revert all the network settings to their default state. Just make sure to save all your WiFi passwords before proceeding.

Here are the steps to reset network settings in iPhone or iOS:

  1. Launch the Settings app and go to the General section.
  2. Choose the Reset tab within General settings.
  3. Tap on the Reset Network Settings command.

  4. Restart your Safari browser.

Once the reset is complete, connect to your WiFi and check if the error message has disappeared or not.

Performing a network reset would also reset the carrier data, APNs, and WiFi passwords. However, with most of these data synced with your Apple ID, restoring them wouldn’t be much trouble.

Also, make sure that you disable the cheap or free VPN services that are generally shared IP addresses with multiple users.

    We resolved this by changing the Search Provider for Safari (iOS 15) to Bing (Settings > Safari > Search Engine change to Bing or to any other search provider if Bing is the issue).
    Perform one search using this new provider, then change it back to the original ‘problem’ provider.
