The main reasons and solutions for Windows SmartScreen cannot connect include: 1. Check whether the network connection is normal and ensure that you can access Microsoft-related websites; 2. Turn off third-party security software to test for conflicts; 3. Reset SmartScreen settings and related system services; 4. Modify group policy or registry to adjust networking permission settings.

Windows smartscreen can\'t be reached right now

The problem you encounter with "Windows SmartScreen can't be reached right now" is usually due to a network or setup barrier when the system tries to connect to Microsoft's services. SmartScreen is a security feature for Windows that detects potential malware and phishing sites. When it prompts that it cannot connect, it is not necessarily a big problem, but it may affect part of the security protection capability of the system.

Windows smartscreen can't be reached right now

Here are some common reasons and solutions for your reference:

Windows smartscreen can't be reached right now

1. Check if your network connection is normal

This is one of the most common reasons. If the computer cannot access the Microsoft server, SmartScreen will show that it cannot connect.

  • Make sure you can open web pages normally, especially Microsoft-related sites (such as Microsoft.com)
  • If you are in a corporate or school network, it may be that the firewall or proxy restricts access
  • Try switching to Wi-Fi or wired network to see if there is any improvement

If you are sure that the network is fine, you can continue to troubleshoot.

2. Turn off temporary tests of third-party antivirus software or firewalls

Some third-party security software (such as Kaspersky, Turfur, etc.) may intercept SmartScreen's networked requests.

  • Temporarily close third-party security software (not just notification bar icon, but actually exit the process)
  • Then restart the Explorer or PC
  • Try to open a program with unknown origin again to see if it will also prompt that SmartScreen cannot connect

If you find that the problem disappears after closing, it is basically caused by conflict. You can choose to replace compatible security software, or allow SmartScreen to function properly in settings.


Sometimes errors in system components can also cause this problem. You can try to fix it manually:

  • Open Settings > Apps > Optional Features > More Windows Features

  • Find and make sure "Windows Defender SmartScreen" is enabled

  • You can also try to fix the system files through the command prompt:

     sfc /scannow

In addition, check whether the following key services are in operation:

  • Windows Security Center Service
  • Windows Update
  • Network List Service

Once these services are disabled or stopped, they may indirectly affect the functionality of SmartScreen.


4. Modify Group Policy or Registration (Advanced User)

If you are an enterprise or advanced user, it may be because local policies limit SmartScreen's networking behavior.

  • You can try to enter gpedit.msc (Group Policy Editor)
  • Navigate to: Computer Configuration > Administrative Templates > Windows Components > Microsoft Defender SmartScreen
  • Make sure "Block Microsoft Defender SmartScreen Networking" is not enabled

If you are using the home version of Windows and do not have the gpedit tool, you can achieve similar effects by modifying the registry, but this requires a certain technical foundation, so it is recommended to operate with caution.


Basically, these common investigation directions. Although the problem is not big, if it cannot be restored for a long time, it may mean that there is conflict between certain settings or software. Don't worry too much if it appears occasionally, but if you are prompted frequently, it is recommended to exclude it one by one according to the above method.
