How to fix network error in MuMuPlayer 12?

If you encounter a Network Error message during emulator download/update or when running an application in the emulator, follow these steps to resolve the issue:

1. Check the network environment

• Ensure your computer’s network connection is active.
• Test by switching to a different network to rule out issues with your original network.
• If you’re connected via campus or corporate networks, these may block emulator/game usage. Switch to another network and check if the issue resolves.
• If using Wi-Fi, try switching to a wired connection for stability.

2. Verify IP and DNS address consistency

Click https://nstool.netease.com/ to check whether the network IP address and DNS address are in the same state or city.

2.1 If they are different

After updating the DNS address, save the changes and restart the computer and try again. The method of querying and changing the DNS address is as follows:

(1) Query the DNS address: press "Win+R", enter "CMD" and press Enter to open the command window, enter "ipconfig /all", find the DNS address of the current network in the "DNS server" line, as shown in the figure below: "10.224.112.2";

(2) Change the DNS address: In the network connection location of the computer, right-click "Open Network and Internet Settings", click "Change Adapter Options", click the connected network (if the connected network is a wired network, click "Ethernet" ; If the connected network is a wireless network, click "Wi-Fi"), right-click the network and click "Properties", drop down in "Network" and find "Internet Protocol Version 4 (TCP/IPv4)", double-click to open the property window, After selecting "Use the following DNS server address", fill in the "Preferred DNS server" line.

2.2 If they are the same

you can try to change the DNS address of the computer to 114.114.114.114, 223.5.5.5, 101.226.4.6, 223.6.6.6 in turn. After the modification is completed, press "Win+R"-enter "CMD" and press Enter to open Command window - enter "ipconfig /flushdns" - click "Enter", restart the emulator (or emulator installation package) and try again.

Note: Campus network users can change the DNS settings of the computer to the DNS address of the school, and try after restarting the computer.

3. Check the host file

Navigate to the “C:\Windows\System32\drivers\etc” folder and open the “hosts” file (using Notepad or a text document). Check for entries related to netease.com or 163.com. If found, delete them, save the file, and restart the emulator (or installer) to see if the issue is resolved.
