Change Your DNS Server to Google
The most widely confirmed fix for the “Download failed” Zenless Zone Zero error message I can find is to change the DNS server settings to Google. This means changing your default DNS to the Google alternative, which could be more reliable. You can set up a Google DNS by going through the following steps:
- First, activate Run by using its Windows logo + R keyboard shortcut.
- To view network connections, input ncpa.cpl and click OK.
- Right-click Wi-Fi (or other internet adapter) to select Properties.
- Next, double-click on the Internet Protocol Version 4 label in the Networking tab.
- Click Use the following DNS server addresses to access the value boxes for that option.
- Type 8.8.8.8 inside the address box for Preferred DNS.
- Enter the 8.8.4.4 Google value within the box for Alternative DNS.

- To set the DNS values entered, click on OK.
- Restart Windows to finish applying this possible fix.
Free Up Drive Storage Space
A lack of free drive storage space can cause download issues for games. Zenless Zone Zero needs at least 57 GB of free drive storage and more for additional game updates. So, check if you have suitable free drive space for the game like this:
- Click File Explorer’s taskbar shortcut.
- Next, click This PC to view drives.
- Right-click a drive you want to install ZZZ on to select Properties.
- Then, check the free space on the General tab.

If you don’t have sufficient space for Zenless Zone Zero, you’ll need to make space for it. The best way to do that would be to uninstall unneeded software or even other games. You can also free up space by erasing file data, but removing software, as covered on this Microsoft page, is the best way to do it.
Turn Off Internet Protocol Version 6
A few players say they got the “Download failed” Zenless Zone Zero error fixed by disabling IPv6. IPv6 is a newer protocol than IPv4 that you don’t necessarily need to have enabled. You can disable Internet Protocol Version 6 like this:
- Go through steps one to three in resolution one for changing the DNS above.
- Next, unselect the Internet Protocol Version 6 checkbox.
- Click OK to save networking settings.

Install and Utilize a VPN
Players who’ve needed to fix the “Download failed” Zenless Zone Zero error have confirmed that using VPN software and connections has worked for them. So, try downloading and installing a free VPN package, such as Proton VPN, for example. Then, turn on that VPN before downloading Zenless Zone Zero.
Execute Network Commands
Executing network commands might fix network-related issues, causing the “Download failed” Zenless Zone Zero error to occur. For example, flushing the DNS cache with a command can clear corrupted or outdated data there. Try executing some network commands like this:
- First, click the file finder tool on the Start menu or taskbar.
- Search for the Command Prompt app by entering a cmd command in the file finder utility.
- Start Command Prompt by right-clicking on it in your search tool and selecting Run as administrator.
- Next, enter these separate commands by pressing Return after each:
netsh winsock reset
ipconfig /flushdns
ipconfig /registerdns
ipconfig /release
ipconfig /renew

Disable Firewalls
To ensure firewalls aren’t interfering with the Zenless Zone Zero game download, try temporarily disabling them. You can disable Windows Defender Firewall by going through steps one to three on this Microsoft page. If you’ve installed third-party firewalls, disable them via their settings tabs.
The Microsoft Defender Firewall setting
Remember to turn the firewalls back on after the game or update downloads if this potential fix works. However, note that you might also encounter startup issues for the game if it’s not allowed through the firewall. If you do, make sure ZZZ is allowed through your firewall.
I hope one of those potential fixes resolves the “Download failed” Zenless Zone Zero error on your PC. You can also ask the game’s help service for more potential fixes by sending an email to zz******@*******se.com. However, try applying the possible solutions discussed above before contacting ZZZ support.
