About this Mod

NonUpdate Reloaded

Blocking network connections to prevent update checks and reduce Minecraft startup time

Usage

Whether you're a gamer or a modpack creator, you've probably encountered that Minecraft sometimes gets stuck for an unknown reason when starting.

It is possible that network requests for certain mods (e.g. checking for updates, fetching patreon lists) are causing Minecraft's startup time to increase.

However, when you installed a whole bunch of mods, it's not easy to turn it off one by one in their config, and some mods may not be able to turn it off.

This mod might be able to help you by blocking network connections.

To allow network connections to specific hosts, add them to the whitelist in the config (config/nonupdate_reloaded.json).

Configuration

allowServerConnects

Default: true

When this option is true, NonUpdate Reloaded automatically and temporarily allows connections to server addresses when you connect to servers

isWhitelist

Default: true

When this option is true, the list option will be used as a whitelist

When this option is false, the list option will be used as a blacklist

list

Default: [ "$eminecraftservices.com", "$emojang.com", "$eminecraft.net" ]

NonUpdate Reloaded will allow/block addresses in this list

Prefixes

$r

Use regex to match addresses

Example: $r.+\.mojang\.com will match sessionserver.mojang.com or abc.mojang.com:123

$e

Matches when a connection address ends with the address

Example: $emojang.com will match sessionserver.mojang.com or abc.mojang.com:123

$s

Matches when a connection address starts with the address

Example: $swww will match www.mojang.com or www.minecraft.net:123

$c

Matches when a connection address contains the address

Example: $cminecraft will match minecraft.example.com or www.minecraft.net:123

No prefix

Example: hypixel.net will match hypixel.net or hypixel.net:25565

Example2: hypixel.net:25565 will only match hypixel.net:25565

Q&A

I can't join my server!

Please add the server address to the whitelist or set the allowServerConnects option to true in the config

Crash with log java.lang.UnsupportedOperationException: The Security Manager is deprecated and will be removed in a future release

Frequently Asked Questions

NonUpdate Reloaded server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.4). You can switch loaders with one click in the panel.

Is NonUpdate Reloaded compatible with fabric and forge and neoforge and quilt?

NonUpdate Reloaded officially supports fabric, forge, neoforge, quilt for Minecraft 1.21.4, 1.21.3, 1.21.2. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with NonUpdate Reloaded – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if NonUpdate Reloaded consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
