FIXED: Honkai Star Rail Error Code 1001_1 & 1001_3

Players sometimes cannot log in to the Honkai Star Rail servers due to a connectivity issue, mainly Honkai Star Rail’s Error Codes 1001_1 and 1001_3. This error is most likely caused by interrupted network packets, the servers not responding, or their unintentional blocking. These errors prevent the game from being played and prevent any connection to its servers.

If you have been greeted with the same ominous message, don’t fret because the solution to the problem might be simpler than you think.

Check Game Servers

Assuming your game is up-to-date, the next step is to check whether Honkai Star Rail’s servers are up and running. Star Rail is an online game, after all, so functioning servers are key to the game’s playability. If the servers are down, you won’t be able to play the game.

And since the error codes 1001_1 & 1001_3 are related to server connectivity issues, I recommend you verify the servers’ status by checking for any updates by the developers on their official Twitter/X account. 

Turning Off VPN

A VPN redirects your data traffic by placing an intermediary server between you and the servers you might want to connect with. This can produce some nasty packet loss and might be the culprit behind your inability to log in.

To try this solution, turn off any VPN software you might have installed before launching the game. If the solution works, you can always set up a custom network filter in the software. This would allow you to go Star Blazing without turning your VPN off every time.

If this did not work, however, then try using a different VPN such as ProtonVPN, as this also helped fix the issue for players online.

Turning Off Ad Blocker

While you might be thinking about how an Ad Blocker would hinder your ability to access Honkai: Star Rail, if you are using one, there is a high chance that it might be blocking the Star Rail servers themselves. According to the players, AdGuard has been a major culprit.

So, it might be worthwhile to turn it off, especially if you are using AdGuard. If the culprit does come out to be the AdBlocker, you can always whitelist the Star Rail servers by creating your very own ad filter.

Removing AdGuard DNS

One of the more niche fixes for people playing Star Rail on PC through an emulator is removing your AdGuard DNS. For some reason, it keeps falsely detecting Hoyoverse servers as malware/malicious. Many of their users reported having fixed their network problems with the game by turning off their private AdGuard servers.

If you are also an AdGuard DNS user with the same dilemma, removing it would most likely fix the problem. 

To remove the said program, Simply:

1. Type Installed Apps into the Start Menu’s search bar and press Enter.
2. Type AdGuard into the search bar.
3. Press the 3 Dots and then click on the ‘Uninstall’ button.

   

4. Follow the wizard along, and you should be done.

If you are using their System-Wide DNS on mobile devices, simply:

1. Go into your Settings app.
2. Click on Network and Internet Settings.
3. Go into Private DNS, and tap on Off.

Flush Your DNS

Your DNS essentially translates human-readable site names to machine-readable IPs. This means that when your network is on a custom DNS, there is a possibility that you might be unable to reach some IP addresses.

In this case, it could be the reason why Honkai Star Rail Error Codes 1001_1 or 1001_3 decided to pop up. So, it would be a good idea to try clearing it.

To flush your DNS Cache:

PC

1. Type ‘cmd’ into the Start Menu’s search bar and press Enter.

   

2. Once in, type ‘ipconfig /flushdns’ into the Command Prompt, and hit Enter.
3.  If successful, you will be greeted with the message that it has Successfully flushed the DNS Resolver Cache.

   

Android

1.  Open your Chrome Browser.
2.  Type chrome://net-internals/#dns: in the URL Bar.
3.  In the left pane, Select DNS.
4. Tap the Clear Host Cache button in the right pane.

   

For iOS users, simply toggling your Airplane Mode would clear the built-up DNS cache.

Whitelist The Game In Antivirus/Firewall

Similar to the AdGuard DNS fix, your system’s Windows Defender Firewall and Antivirus can oftentimes, mark some of your game files as threats to the system and therefore, these files are quarantined (restricted). Because of this, the game cannot access these files and may run into a variety of errors including the 1001_1 and 1001_3 ones.

Instead of disabling these services entirely and leaving your system open to threats, I recommend whitelisting the game in your Antivirus and Defender directories, so that they will ignore the game and its files and won’t interrupt Honkai Star Rail’s functioning.

Change DNS Servers

If flushing your DNS Cache doesn’t fix Honkai Star Rail Error Codes 1001_1 or 1001_3, changing it to a Public DNS Server could solve the issue. This is because, sometimes a new DNS server allows for better connectivity and a more stable server connection.

While you can use any available public DNS servers, our recommendation would be to go with one of the two:

•  Google’s DNS (8.8.8.8 and 8.8.4.4)
•  OpenDNS (208.67.222.222 and 208.67.220.220).

Contact Support

If nothing else has worked for you, then I recommend contacting the support team and letting them know of your problem. This will allow them to be aware of the errors and hopefully, start working towards fixing them. You can contact Honkai Star Rail Support in-game through the Settings menu. 

My Thoughts On Honkai Star Rail Error Code 1001_1 & 1001_3

Hopefully, the developers of Honaki Star Rail can stay vigilant as they’ve shown to be so far and continue to monitor all the error reports they receive. You should also keep track of the discussions going on in various gaming forums including Reddit and HoyoLab.

One disappointing thing is that the developers don’t take the time to address errors and bugs publically, on any of their social media platforms. This is detrimental to the community as no one can tell if their feedback is being heard. Still, people continue to take to Twitter and other platforms to voice their concerns.

Does anyone know how to fix this Error 1001_1 when using mobile data with Honkai Star Rail? It is not a connectivity issue because I am playing Genshin just fine!.. #honkaistarrail pic.twitter.com/dV2iu9PuJK
