Windows Errors? Fix Them Before They Spread
Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallCrashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minute“Connection Failed, Try Again Later” is a generic Genshin Impact connection or authentication error, not one specific bug. First, try the game on a phone hotspot. If it works there, investigate your home router, ISP, DNS, firewall, or filtering. If it fails on every network, check HoYoverse service status, the installation, account and server selection, and the device.
Use the fixes below in order. They avoid unnecessary reinstalls and follow HoYoverse’s current guidance on VPNs, network switching, router restarts, file repair, CAPTCHA problems, and support requests.
First, check whether HoYoverse is down
Before changing files or passwords, check official in-game announcements and HoYoverse announcements. Try opening HoYoverse account or support pages in a browser, and ask whether friends in the same region see the error. Another HoYoverse game can be a comparison, but it does not prove that Genshin’s servers are healthy.
If the failure began immediately after maintenance, a major patch, or an authentication-system change, wait and monitor official notices. Local troubleshooting cannot repair an outage. Do not claim that servers are down unless an official notice or strong current evidence supports it.

The message can appear before login, after credentials are submitted, while loading into Teyvat, during CAPTCHA, after launcher update checks, or during regional-server and platform-account authentication. Seeing it does not prove that Wi-Fi is disconnected.
The fastest low-risk troubleshooting sequence
- Close Genshin and HoYoPlay completely. Exit the game, then close HoYoPlay from the system tray. Reopen it and retry. If repeated attempts fail, restart the device.
- Disable traffic-routing tools. Temporarily turn off consumer VPNs, Windows or browser proxies, game accelerators, ad-blocking DNS, and network-wide filtering. HoYoverse says these can disrupt both game connections and CAPTCHA verification: general connection guidance and CAPTCHA guidance.
- Restart the router or modem. Unplug it for about 30 seconds, reconnect it, wait for internet service to return, and launch Genshin again.
- Switch networks. Try a phone hotspot, another Wi-Fi network, Ethernet instead of Wi-Fi, or mobile data on a phone or tablet.
- Update the game and launcher. Use HoYoPlay or the official platform store, not third-party files.
- Repair the installation. Use HoYoPlay’s Repair Now or the in-game resource-integrity check described below.
- Check security software and filtering. Review firewall blocks and antivirus quarantine before considering a reinstall.
- Verify account, login method, and server. A wrong platform account or server can look like a connection failure.
- Reinstall only after these tests fail. Confirm that you can access the correct account first.
- Contact HoYoverse support with the diagnostic details and logs requested below.
Use a hotspot to identify the fault
The hotspot test is the most useful controlled comparison because it changes the network without changing the game installation.
| Test result | Most likely implication |
|---|---|
| Works on a hotspot but not home Wi-Fi | Router, ISP routing, DNS, firewall, parental controls, or network filtering |
| Fails on every network on one device | Device, installation, security software, or operating-system issue |
| Works on another device with the same account | Original device or installation issue |
| Fails across devices and networks | HoYoverse service, regional platform, account, or authentication issue |
| Only one account fails | Credentials, login method, account linking, or an account-specific restriction may be involved |
HoYoverse recommends switching between Wi-Fi, mobile data, and wired connections for connection errors: official connection steps. If only a school, workplace, hotel, apartment, or public network fails, use a private connection for testing rather than bypassing organizational controls without permission.
Repair Genshin Impact files
HoYoPlay on PC
- Open the Genshin Impact launcher.
- Use the control beside Start Game.
- Select Repair Now.
- Wait for the scan and repair to finish, then reopen the launcher.

From the login screen or in-game
If you can reach the login screen, select the wrench icon and run the resource-integrity check. If you can enter the game, use Paimon Menu → Settings → Resources → Check Resource Integrity. Restart after the check completes. The documented resource-repair paths are listed by HoYoverse at this support article.
Mobile, PlayStation, and Xbox
Install updates and use the platform’s official repair or reinstall mechanism. Download only through HoYoPlay, Google Play, the App Store, PlayStation Store, or Xbox Store. HoYoverse’s cross-platform update guidance is at official update and download support.
Fix CAPTCHA and login-web errors
Use this section when CAPTCHA is blank, never appears, or fails verification. It is not a universal cure for every connection error.
- Disable VPNs, proxies, accelerators, and filtering tools.
- Switch to another network.
- Restart the router for about 30 seconds.
- Close Genshin and HoYoPlay completely.
- On PC, open
Genshin ImpactGenshin Impact gameGenshinImpact_DatawebCaches. - Delete the files inside
webCaches, then restart the game.
HoYoverse documents this cache location and procedure at CAPTCHA Fails to Load or Verify.

Check firewall, antivirus, and DNS filtering
- Review recent antivirus notifications and quarantine items.
- Confirm that HoYoPlay, Genshin Impact, and the game executable are not blocked.
- Add the official launcher and game folder to the security product’s allowed list when necessary.
- Prefer an exception over permanently disabling protection. If you disable antivirus briefly for a test, turn it back on immediately.
- Review router parental controls, custom DNS, firewall rules, and network-wide ad blocking.
Security software interference is a possible cause, not a diagnosis for every player. HoYoverse’s guidance is to check quarantine and whitelist settings: official error guidance. Do not download replacement DLLs, registry “fixes,” unofficial launchers, or network-fix executables.
DNS changes are an optional advanced diagnostic, not a guaranteed solution. A hotspot result is safer and more informative than publishing or testing stale server-IP lists. Unknown proxies can expose credentials and create regional or security problems.
Confirm the account, login method, and server
A successful internet connection does not guarantee that the selected account flow is correct.
- Check the HoYoverse email or username and password.
- Use the same login method originally used. Email login is not automatically the same account as Google, Apple ID, or Game Center login.
- On PlayStation or Xbox, verify the correct platform account and account-linking status.
- Confirm the intended regional server. On PlayStation, the PlayStation Network account’s region determines server selection.
- Do not create a new account as a routine test; that can make progress and linking confusion worse.
HoYoverse explains login methods, server selection, PlayStation regions, and cross-platform credentials at this account article and this cross-platform guidance.

Platform-specific checks
Windows PC
- Update Windows and restart after updates.
- Check system date and time if authentication or CAPTCHA behaves abnormally; a badly incorrect clock can interfere with secure web connections, but this is a diagnostic clue rather than a confirmed universal fix.
- Test without VPN, proxy, accelerator, or corporate filtering.
- Review antivirus quarantine and firewall rules.
Community reports associate some older Windows installations with TLS or CAPTCHA behavior, but those reports do not establish HoYoverse’s current compatibility policy. Update Windows or test on a supported newer device rather than installing unofficial TLS proxies. Community examples include this report and this report.
Android and iPhone/iPad
- Switch between Wi-Fi and mobile data.
- Toggle airplane mode or restart the phone when using cellular data.
- Install the latest version from the official store.
- Do not clear all app data unless you know the correct account credentials and login method.
PlayStation and Xbox
Use the console’s official update and reinstall tools. Remember that console account-linking and regional-server behavior can differ from the PC email/password flow. Test another platform only when the HoYoverse account is already linked correctly.
When reinstalling is justified
Reinstall when Repair Now cannot restore files, the installation is incomplete or corrupted, the launcher itself is malfunctioning, another device works on the same network, or HoYoverse support recommends a clean installation.
- Confirm account access and the correct login method first.
- Check available storage and bandwidth.
- Uninstall only the client; this does not delete the HoYoverse account.
- Download from an official launcher or platform store.
Reinstallation cannot fix a HoYoverse outage, wrong server, incorrect login method, or ISP restriction. HoYoverse’s official update and reinstall guidance is at this support article.

Quick Recap
What not to do
- Do not treat the generic message as proof of an account ban or hacking.
- Do not reinstall before testing a hotspot and checking service announcements.
- Do not use old community server-IP lists as current authoritative data; one example is this older community article.
- Do not install unofficial DLLs, proxies, registry files, or “network repair” tools.
- Do not repeatedly reset passwords or create accounts before confirming the original login method.
- Do not leave antivirus protection disabled.
- Do not buy a VPN, router, antivirus subscription, or faster internet connection as a default fix; none addresses every possible cause.
