Common issues
I don’t see a reCAPTCHA
If you don’t see a reCAPTCHA, try these steps in order:
Check for malware on your computer. Malware is malicious software that can be installed on your computer without your knowledge. Some malware can cause Google to show this message. Learn how to detect and remove malware.
Contact your network administrator. If you share a Wi-Fi network with others, like at a school or business, another computer in your network might be sending automated searches to Google. Your network administrator or IT professional might be able to locate and stop the source of the problem.
Reset your modem or router. If you don’t have a network administrator, try resetting your modem or router to see if that fixes the issue.
Once the automated searches have stopped, you should be able to search normally on Google.
I shouldn’t be getting blocked
The blocking might be related to your use of a Virtual Private Network (VPN) browser plugin or program. You might try uninstalling the VPN from your computer or network and see if that makes a difference.
Some VPNs send traffic that violates the law or websites’ terms of service. If you’re an Internet Service Provider (ISP), explain to your users why they should uninstall these VPNs. When the abuse to Google’s network stops, we automatically stop blocking the IP(s)/ISP(s) that were sending the bad traffic.

It’s written at the bottom of the page:
Our systems have detected unusual traffic from your computer network.
This page checks to see if it’s really you sending the requests, and
not a robot. Why did this happen?

Because of google find un-usual traffice from your end. so google just wants to confirm that user is human it is not a any pre-command bug which can give un-usual traffice to google server.
