Google Unusual Traffic Error on iPhone 18 Pro? How to Fix

Some users have run into this issue when they try to Google search something on their iPhones. They receive the message “Our Systems Have Detected Unusual Traffic…” and they are asked to complete a CAPTCHA. This wouldn’t be so terrible, except that for those affected, they usually receive this message repeatedly, making what should be a simple Google search a pain.

In this article, we’ll explain some of the possible causes of this problem and how you can fix it.

Why your iPhone/Safari keeps saying “unusual traffic”

Well, you are getting this message because Google has detected unusual traffic – not helpful. So, why is Google detecting unusual traffic? There are a few possibilities, including:

• You are using public Wi-Fi, and many other people on the network are also searching Google.
• You and a few others on your home Wi-Fi network are searching Google.
• You are using a VPN.
• You Googled many things really fast, maybe?

It also seems that this problem often persists, which means that once you are flagged as the source of unusual traffic, you may continue to receive this message.

How to fix the “unusual traffic” issue

Some users have said that this problem goes away for them on its own. Others only have this problem occasionally. However, if you are continually getting this message, there are a few things you can try.

Restart your iPhone 18 Pro

Simultaneously press and hold the side button and either volume button until the sliders appear, then drag the Power Off slider.

Clear your browser history and cookies

If you do this, you may need to sign back into many websites. Anything you have saved in autofill will not be affected, and your Keychain passwords will still work.

To turn off a VPN in iPhone Settings:

1. Open Settings on your iPhone 18 Pro.
2. Scroll down and find VPN. Toggle the switch to turn it off.
