How to Fix Internal Exception java.net.SocketException Connection reset Error

The “Internal Exception: java.net.SocketException: Connection reset” error can seem like a simple internet connectivity issue at first glance, but it’s much more than that. This error has been around for years and doesn’t have a single fixed cause.

Accordingly, users have managed to resolve it with various unlikely methods, like creating a new installation profile or adjusting the graphic settings. Others have placed the blame on server-side issues, although the devs continue to deny this.

Leaving that controversy aside, the important detail is that even though there’s no official patch from the devs, there are time-tested solutions that have helped numerous users. We’ve compiled a list of such fixes in this article.

How to Fix “Internal Exception java.net.SocketException Connection reset” Error?

Before anything, restart your PC and router. Once that’s done, run Minecraft as an administrator. If the error persists, move on to the solutions to start troubleshooting.

VPN-related Fixes

We’ve found this error to be primarily related to VPNs, both in good and bad ways. Some users reported that this error didn’t occur when connected to a VPN. Others found that a VPN didn’t help at first, but after trying a few different clients and server locations, the error no longer occurred.

On the other hand, some users first encountered this error when playing with a VPN. In such cases, it would be best to disable the VPN instead.

Specifically, after limited testing, the Minecraft Community Support Discord members found Hamachi VPN to be one of the main causes of this error. If you’re using Hamachi VPN as well, we recommend uninstalling Hamachi, or atleast disabling it, and checking if the error is resolved.

Check Network Configurations

The reason VPNs have resolved this issue for so many users has to do with your IP address on the current network. As such, simply connecting to a different network could be all that’s needed to fix this error.

Configuring a couple of global TCP settings has also been one of the most successful fixes for this error. Here’s how you can apply this fix:

1. Press Win + R, type cmd , and press CTRL + Shift + Enter.
2. Type netsh interface tcp show global and press Enter.
   
3. Check the value of Receive-Side Scaling State. If it’s disabled, type netsh interface tcp set global rss=enabled and press enter.
4. Next, check the value of Receive Window Auto-Tuning Level. If it’s disabled, type netsh interface tcp set global autotuninglevel=normal and press enter.
   
5. Exit command prompt, launch Minecraft, and check if the error is resolved.

If the error persists, we recommend manually changing the DNS server as the next step. If that doesn’t help either, execute the commands listed below in command prompt. They’ll perform a bunch of useful actions, including clearing your DNS cache and renewing your IP.

• ipconfig /release
• ipconfig /flushdns
• ipconfig /renew

Java-related Fixes

The official Minecraft launcher handles Java installation for Minecraft automatically, so generally, it’s not something the player needs to worry about. But when running dedicated servers on older Java versions, it is essential.

First, you’ll want to download and install the JDK. Some users have had success with the latest version, while others had to install older versions like JDK16 to resolve the error. So essentially, it’s worth trying out different versions.

Next, you’ll also want to ensure JDK is allowed through the firewall. If you’re using any third-party firewall, we recommend temporarily disabling it to check if the error gets fixed. In the case of Windows Firewall, here are the steps you should follow:

1. Press Win + R, type control firewall.cpl , and press Enter.
2. Click on Allow an app or feature through Windows Defender Firewall.
   
3. Click on Change settings and accept any prompts.
   
4. Scroll down and select OpenJDK Platform Binary. Ensure the checkboxes in both the Private and Public fields are enabled.
5. If you don’t find this entry, click on Allow another app > Browse.
   
6. Select javaw.exe and select Open > Add from the following location:
   C:\Program Files (x86)\Minecraft\runtime\java-runtime-alpha\windows-x64\java-runtime-alpha\bin\
7. Finally, press OK, launch Minecraft, and check if you still get the error.

Migrate to Microsoft Account

Some users found that the error stopped occurring after they migrated their Mojang accounts to Microsoft. The Minecraft Help Center has extensive guides that answer most of the common queries regarding the migration process, so we highly recommend referring to said guides if you need help with the migration.

Workaround with Epic Games Launcher

If you start downloading any random game in the Epic Games Launcher and then try to launch Minecraft, chances are, you won’t encounter the error. There’s no sound reasoning for why this workaround works, but the important part is that it did let countless users play without the error, so it’s worth trying.

Create New Launcher Profile

This is another solution recommended by Mojang, with a proven record. Here’s how you can use a new installation profile:

1. Run the Minecraft launcher and click on Installations.
2. Click on New Installation and name it as you please.
3. Set the version to an older one (e.g., 1.18.2 ) and try launching Minecraft.

Check Visual Settings

Downgrading the game graphics has resolved this error for numerous players. Even teleporting to an unmodified area has been helpful in some cases. This is possibly because the server is unable to handle how fast you’re loading the world at your current settings. Here’s what we recommend:

1. In Minecraft, enter a different world if necessary and go to Options > Video Settings.
   
2. First, turn off Full screen and try lowering the resolution.
   
3. Restart Minecraft and check if the error is resolved.
4. Reduce the Render Distance to 12 chunks or lower, then restart and check again. Additionally, toning down the Graphics and Simulation distance settings can help with lag.
   
5. Finally, one user also found that uninstalling all the texture packs fixed the problem. So, if the error still persists, this may be worth trying.

Server-related Fixes

There are a number of server-related solutions useful for resolving this error. We recommend trying them in the following order:

• First, increase the server memory. The default amount (1GB) is known to cause connection issues and crashes as the limit is easily reached.
• Try switching to a lower server version.
• If you’re the host, you could try copying the private server files to another location. If you encounter problems moving any files, said files could be the cause of the error.
• Additionally, starting a new world with a new server host could also help.

Reinstall Minecraft

If the error still persists, uninstalling and reinstalling Minecraft is likely the final option at this point. You’ll want to copy the saves from the .minecraft folder in %appdata% before uninstalling, though. Additionally, a PC reset is overkill for this error, but if you’ve backed up your files elsewhere and playing Minecraft means a lot to you, then this is an option to consider as well.

Ошибка java.net.SocketException: Conection reset – как исправить

Сразу сообщу, что если у вас проблема с игрой майнкрафт, то листайте в самый конец статьи, а пока информация для разработчиков и программистов.

В этом примере мы поговорим о java.net.SocketException. Это подкласс IOException, поэтому это проверенное исключение, которое сигнализирует о проблеме при попытке открыть или получить доступ к сокету.

Настоятельно рекомендуется использовать самый «определенный» класс исключений сокетов, который более точно определяет проблему. Стоит также отметить, что SocketException, выдаётся на экран с сообщением об ошибке, которое очень информативно описывает ситуацию, вызвавшую исключение.

Простое клиент-серверное приложение

Чтобы продемонстрировать это исключение, я собираюсь позаимствовать некоторый код из клиент-серверного приложения, которое есть в java.net.ConnectException. Он состоит из 2 потоков.

• Поток 1 – SimpleServer, открывает сокет на локальном компьютере через порт 3333. Потом он ожидает установления соединения. Если происходит соединение, он создает входной поток и считывает 1 текстовую строчку, от клиента, который был подключен.
• Поток номер 2 – SimpleClient, подключается к сокету сервера, открытого SimpleServer. Он отправляет одну текстовую строчку.

Получается, что 2 потока будут в разных классах, запущенных двумя разными основными методами, чтобы вызвать исключение:

Как вы можете видеть, я поместил в SimpleClient 15-секундную задержку, прежде чем попытаться отправить свое сообщение. К тому моменту, когда клиент вызывает sleep(), он уже создал соединение с сервером. Я собираюсь запустить оба потока, и после того, как клиент установит соединение, я внезапно остановлю клиентское приложение.
Вот что происходит на стороне сервера:

Мы получаем исключение SocketException с сообщением «Сброс подключения». Это происходит, когда один из участников принудительно закрывает соединение без использования close().

Конечно, вы можете сделать оперативное закрытие соединения, не закрывая приложение вручную. В коде клиента, после ожидания в течение 15 секунд (или меньше), вы можете выдать новое исключение (используя throws new Exception ()), но вы должны удалить finally, иначе соединение будет нормально закрываться, и SocketException не будет сброшен.

Как решить проблему с SocketException

SocketException – это общее исключение, обозначающее проблему при попытке доступа или открытия Socket. Решение этой проблемы должно быть сделано с особой тщательностью. Вы должны всегда регистрировать сообщение об ошибке, которое сопровождает исключение.

В предыдущем примере мы видели код сообщения. Это происходит, когда один из участников принудительно закрывает соединение без использования close(). Это означает, что вы должны проверить, был ли один из участников неожиданно прерван.

Также может быть сообщение «Слишком много открытых файлов», особенно если вы работаете в Linux. Это сообщение обозначает, что многие файловые дескрипторы открыты для системы. Вы можете избежать этой ошибки, если перейдете в /etc/sysctl.conf и увеличите число в поле fs.file-max. Или попытаться выделить больше стековой памяти.

Конечно, можно встретить много других сообщений. Например, «Ошибка привязки», где ваше соединение не может быть установлено, поскольку порт не может быть привязан к сокету. В этом случае проверьте, используется ли порт и т. д.

Если у вас проблема с minecraft, то чтобы решить проблему попробуйте сделать следующее:

1. Обновите джаву, скачайте по ссылке https://www.java.com/ru/download/ новую версию и установите;
2. Возможно блокирует антивирус или брандмауэр. Отключите антивирус и добавьте minecraft в список исключения в брандмауэре (или его можно выключить на время).
3. При запуске игры, в правом нижнем углу отображается версия игры, если у вас не последняя версия, то обновите.
4. Если у вас много расширений и модов, то это может приводить к багам, удалите последние установленные моды – это может решить проблему.
5. Если вы используете платный сервер и у вас закончилась подписка, то опять же у вас будет такая ошибка.
