✅ Step‑by‑Step Fixes to Try
Try these in order until one works. Depending on whether you’re on PC, console, or mobile, some steps may or may not apply.
| Step | What to Do | Why It Helps |
|---|---|---|
| 1 | Check server status / maintenance | If servers are down, there’s nothing you can do except wait. |
| 2 | Switch network (Wi-Fi ↔ mobile data / another Wi-Fi / hotspot) | Sometimes your ISP or current network is blocking or routing badly. Many reports say switching fixed it. |
| 3 | Change DNS settings | Use public DNS like 1.1.1.1 / 1.0.0.1 (Cloudflare) or 8.8.8.8 / 8.8.4.4 (Google) |
| 4 | Flush DNS cache (PC) | On Windows: open Command Prompt and ipconfig /flushdns. This clears stale DNS mappings. |
| 5 | Disable VPN / Proxies / Ad-blockers / Firewalls | These might block or reroute connections the game needs. Many users confirmed disabling these helped. |
| 6 | Clear game cache / data | On mobile: clear app cache or data. On PC: delete the game’s cache or “HoYoverse” local folders. |
| 7 | Repair / verify game files | In the launcher, use the “Repair” option (if available) to fix corrupted files. |
| 8 | Reinstall the game | If corruption is severe, a fresh install can help. |
| 9 | Contact support | If none of the above work, reach out to HoYoverse / the game’s official support. |
