Here’s what to do about how to prevent downloads from being blocked by firewalls: 1. Adjust the firewall settings: Press the shortcut key win+r, enter in the run box firewall.cpl and click enter. Click Allow the program or feature through Windows Firewall. Click Change settings option. Tick Google Chrome, which is Google Chrome. Click the OK button to remove the firewall from Google Chrome. 2. Check your browser settings: Open it, click on the three dots in the top right corner, and select “Settings”. In the settings page, find the “Advanced” option and expand it. In the “Download content location” section, check that the default download path is correct, making sure it’s an accessible folder with enough storage space. If you want, you can click the “Change” button and choose a suitable download path. 3. Turn off safe browsing: In your browser’s settings, find the “Privacy and Security” section and click on “Security”. Here, you can see the “Safe Browsing” option, which may block some downloads that are considered unsafe or suspicious. If you’re sure that the file you’re downloading is safe, you can try turning off Safe Browsing for a while and downloading again. However, turning off this feature may reduce the security of your browser, and it is recommended to turn it back on after the download is complete. 4. Check your network connection: Make sure your network connection is working and stable. An unstable network may cause interruptions or abnormalities in the download process, and the browser may mistakenly judge it as needing to be blocked. You can try switching to a different network environment, such as switching from Wi-Fi to a mobile data network, or restart your router and try downloading again. 5. Check antivirus settings: Firewalls or antivirus software may block the download of certain files. Check the settings of the firewall and antivirus software installed on your computer to see if there are any relevant blocking rules. If you find that there are blocking rules affecting downloads, you can add or specific download file types to the whitelist to allow them to pass the inspection of firewalls and antivirus software. Different firewall and antivirus software settings may differ, and you can refer to the corresponding software help documentation for specific operations. 6. Confirm file security: If the browser blocks the download because the file may contain malware or viruses, you can use an online virus scanning tool to scan the file link to determine if the file really has security issues. If the scan results show that the file is safe, it may be a misjudgment by the browser and you can try downloading it in another way, such as using a download manager or downloading it in a different browser. 7. Clear browser cache and cookies: Data in browser cache and cookies can cause download issues. In the book, tap the three dots in the top right corner, select “More tools,” and then tap “Clear browsing data.” In the pop-up window, choose to clear cached images and files, cookies, and other data, and click the “Clear Data” button. Once the cleanup is complete, close and reopen the browser and try to download the blocked content again. 8. Try downloading using incognito mode: Incognito mode does not save browsing history, cookies, and cache data, which can sometimes bypass some blocking issues. Click the three dots in the top right corner, select “New Incognito Window”, and try to download the blocked content in incognito mode. If the download is successful, it means that some settings or data in normal browsing mode may be causing the blocking issue. With the above steps, you can usually solve the problem of downloads being blocked by firewalls. If the problem is complex or difficult to solve, it is recommended to seek professional technical support or contact Chrome’s official customer service for assistance.
