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

Does NonUpdate Reloaded need to be installed on the Minecraft server?
No. Modrinth marks NonUpdate Reloaded as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.
Which version and loader does NonUpdate Reloaded require?
Use a file for fabric, forge, neoforge, quilt and your exact Minecraft version. Supported versions include 1.21.4, 1.21.3, 1.21.2. Files for different loaders are not interchangeable.
NonUpdate Reloaded is not working – what should I check?
First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
