Quick Answer: How to Fix the Error
To fix the Honkai Star Rail resource download failed error, the most effective method is to clear your downloaded resource cache.
- On PC: Open the HoYoPlay Launcher, click the menu icon beside “Start Game”, navigate to Game Settings > Advance Settings, and click “Clear Downloaded Resource cache”.
- On Android: Go to your device Settings, find Apps, select Honkai Star Rail, tap Storage, and hit “Clear cache”.
- On iOS: Open the game, navigate to Settings, select “Other”, and choose “Clear cache”.
Whether you are downloading a massive new patch or installing the game for the first time, encountering a download failure can halt your journey through the cosmos. The “Resource download failed. Check your network settings and try again” error message is incredibly common across PC, Android, and iOS platforms.
Fortunately, by tweaking a few launcher settings, clearing leftover data, or optimizing your network, you can resolve this issue swiftly. Below is a comprehensive guide to getting your game updated and running smoothly.
Common Causes of the Download Failure
According to the official HoYoverse Help Center, update and download failures usually stem from a few predictable culprits. Understanding these can help you target the right fix:
- Unstable Networks: Unstable internet connections or strict network restrictions can easily interrupt the download process.
- Security Software Interference: Your firewall or antivirus software might mistakenly block the game files or launcher.
- Insufficient Storage Space: Downloads can freeze if your device runs out of storage space mid-installation; ensure you have at least 20 to 25 GB free.
- Corrupt Data: Incomplete downloads can lead to corrupted game files.

Advanced Troubleshooting Steps
If clearing the cache (detailed in the Quick Answer above) did not solve your issue, work your way through these advanced troubleshooting methods.
1. Network Adjustments & VPN Tricks
- Change Networks: Try connecting to a different network, such as using your mobile data instead of Wi-Fi.
- Restart Router: Restarting your router can help refresh the network connection and resolve temporary hang-ups.
- VPN Usage: Interestingly, while VPNs can sometimes throttle or block downloads and should generally be disabled, some players found success by temporarily turning on a VPN, letting the game load past the error, and turning the VPN off once inside.
2. Repair Game Files & Grant Permissions
- Run as Administrator (PC): Right-click the HoYoPlay launcher and select “Run as administrator” to ensure the game has the proper permissions for downloading and installing files.
- Restore/Repair Files: Open the launcher, click the three lines (menu), and select the option to verify or repair your game files. After the repair completes, launch the game to check if the error is fixed.
| Platform | Recommended Fixes | Fallback Solution |
|---|---|---|
| PC (Windows) | Clear Downloaded Resource Cache via HoYoPlay; Run as Administrator. | Use launcher repair tool or disable antivirus temporarily. |
| Android | Settings > Apps > Honkai Star Rail > Force Stop & Clear Cache. | Switch from Wi-Fi to Mobile Data (or vice versa). |
| iOS | In-Game Settings > Other > Clear Cache. | Reinstall the app entirely if storage allows. |
If all of these steps fail, your last resort is to completely uninstall and reinstall the game.
