How to fix HSR error code 1001_1 in Honkai Star Rail

Honkai Star Rail error code 1001_1 is a login failure: the game client cannot complete its connection to HoYoverse's login servers, so you stay stuck on the login screen. It is usually caused by your own connection (unstable Wi-Fi, DNS, VPN or firewall) or by server maintenance. Check the official channels for an outage first, then restart the game, switch networks, flush or change DNS and disable VPNs.

This guide covers what HSR error 1001_1 means, how to tell a server problem from a local one, and the fixes in the order that saves the most time on PC and mobile.

What does HSR error code 1001_1 mean?

HSR error code 1001_1 means the Honkai Star Rail login request did not get a valid response from the server. The game shows it on the login screen, often in a loop where every retry fails the same way. Players report it on PC, Android and iOS, and it tends to spike after big version updates, when a large share of the player base logs in at the same time.

The code does not point to one single fault. The common causes are:

• Server maintenance or an outage on HoYoverse's side, typically around patch days
• An unstable or slow internet connection, including weak Wi-Fi or a congested mobile network
• DNS problems: an outdated DNS cache or a slow or faulty DNS resolver from your provider
• A VPN, proxy or third-party firewall that blocks or reroutes the game's traffic
• Less often, damaged or incomplete game files after an interrupted update

Because the error is a connection failure, the fastest fix depends on whether the problem sits with the servers or with your device. The next section shows how to tell them apart.

Check if Honkai Star Rail servers are down first

Checking the server status is the first step for error 1001_1, because no local fix works during an outage. HoYoverse does not run a public status page for Honkai Star Rail, but it announces maintenance windows and login problems on the official Honkai Star Rail account on X and in its official community channels.

Use this quick test to locate the problem:

• If an announcement mentions maintenance or login issues, wait until it ends before trying again.
• If many players report 1001_1 at the same moment, the cause is almost certainly server side.
• If the game works on another device or network but not on yours, the problem is local, so continue with the fixes below.

Waiting it out is a legitimate fix. Repeated login attempts during an outage do not speed anything up.

How to fix Honkai Star Rail error 1001_1

Work through these fixes in order, testing a login after each one. The early steps are quick and solve most cases.

1. Close the game completely and relaunch it. On mobile, swipe it away from the recent apps list; on PC, make sure no game process is left running.
2. Switch networks: move from Wi-Fi to mobile data or the other way around. If the game logs in on the other network, your router or provider is the cause.
3. Restart your router and modem, and on PC prefer a wired Ethernet connection for a stable link.
4. Turn off any VPN or proxy, and temporarily pause third-party firewall or security software to test whether it blocks the game.
5. Log out from the login screen and sign back in to your HoYoverse account.
6. Flush your DNS cache, and switch to a public DNS resolver if the error continues (see the next section).
7. Repair the game files: in the Epic Games Launcher, open your Library, select the three dots next to Honkai: Star Rail, choose Manage and then Verify; in the official HoYoverse launcher, use its repair or verify option for the game.
8. Reinstall the game as a last resort if the files keep failing.

If a firewall turns out to be the cause, add an exception for the game instead of leaving protection off. Our guide on managing Windows Firewall rules for programs and folders shows where those rules live.

Flush DNS and change DNS servers on Windows

Flushing the DNS cache fixes error 1001_1 when Windows still holds an outdated address for the game's servers. It takes a few seconds:

1. Open Command Prompt (search for cmd in the Start menu).
2. Type ipconfig /flushdns and press Enter.
3. Wait for the message that the DNS Resolver Cache was successfully flushed, then restart the game.

If the error returns, your provider's DNS resolver may be slow or unreliable. Switch your network adapter to a public resolver such as Cloudflare (1.1.1.1 and 1.0.0.1) or Google Public DNS (8.8.8.8 and 8.8.4.4). On Android, change the DNS in the settings of your Wi-Fi network instead. To see what Windows has cached before and after the flush, read how to display all cached DNS entries on Windows, and for a filtering resolver, see our look at AdGuard DNS.

When to contact HoYoverse support

Contact HoYoverse support when error 1001_1 persists for more than a day on several networks, with no maintenance announced. At that point the cause may be tied to your account or region, which only the developer can check.

You can reach support through official channels only:

• In the game, open the phone menu (Esc on PC) and choose Bug Report to file a ticket, if you can get in on another device.
• If you cannot log in at all, use the contact options on HoYoverse's official customer support site or the official Honkai Star Rail website, not contacts posted by third parties.

Include your UID, platform, server region, the time the error started and the fixes you already tried. Never share your password, and ignore anyone offering paid "unban" or login tools: they are a common route to account theft.
