NonUpdate Reloaded

The Problem of Minecraft's Slow Startup

Many players and modpack creators have encountered situations where Minecraft gets stuck during startup for no apparent reason. Often this happens because various modifications send network requests—for example, checking for updates or loading subscriber lists from platforms like Patreon. These requests significantly increase the game's loading time.

Since turning off such checks in each mod's settings is practically impossible in large modpacks (especially when some don't provide this option), we've created an alternative solution.

How the Mod Works

NonUpdate Reloaded automatically blocks unnecessary network connections, significantly reducing the game's startup time. At the same time, full control remains with the user.

Flexible Configuration

Main Configuration Parameters

All mod settings are located in the config/nonupdate_reloaded.json file:

allowServerConnects Default value: true If set to true, the mod automatically allows connections to server addresses when connecting to them.

isWhitelist Default value: true When true, uses the list as a "whitelist" (allows specified addresses), when false» - as a "blacklist" (blocks specified addresses).</p> <p><strong>list</strong> Default list: <code>[ "$eminecraftservices.com", "$emojang.com", "$eminecraft.net" ]</code> NonUpdate Reloaded allows or blocks addresses from this list depending on settings.</p> <h3>Address Filtering Rules</h3> <p>Various prefixes are available for working with network addresses:</p> <p><strong>$r</strong> - regular expressions Example: <code>$r.+┐\.mojang\.com</code> matches addresses <code>sessionserver.mojang.com</code> and <code>abc.mojang.com:123</code></p> <p><strong>$e</strong> - ends with Example: <code>$emojang.com</code> matches addresses <code>sessionserver.mojang.com</code> and <code>abc.mojang.com:123</code></p> <p><strong>$s</strong> - starts with Example: <code>$swww</code> matches addresses <code>www.mojang.com</code> and <code>www.minecraft.net:123</code></p> <p><strong>$c</strong> - contains Example: <code>$cminecraft» matches addresses</code>minecraft.example.com<code>and</code>www.minecraft.net:123

No Prefix Example:

• hypixel.net matches hypixel.net and hypixel.net:25565
• hypixel.net:25565 matches only the specific server with the port

Troubleshooting Common Issues

Cannot Connect to Server

Add your server’s address to your whitelist in the mod settings. Or set allowServerConnects to true to automatically allow connections when connecting to any servers.

Java Startup Error: Java .lang: UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release

This issue may occur with new versions of Java Runtime Environment. To replace the error with just a warning, add `-Djava.security.manager=allow» to your launcher settings.
