Step-by-Step Fixes: Conquer Mod Mayhem Now! 🛠️

Follow these proven steps in order—90% of gamers fix it by step 3. Patience pays off! 👍

1️⃣ Quick Network Reset (2 Minutes)

Restart your router, flush DNS: Open Command Prompt (Windows) or Terminal (Mac/Linux) and run:

ipconfig /flushdns (Windows)
sudo dscacheutil -flushcache (Mac)

Disable VPN/proxy. Test on mobile hotspot if needed. Relaunch installer—boom, fixed for many!

2️⃣ Bypass Firewall & Antivirus Blocks

Temporarily disable Windows Defender, Avast, or Norton. Add exceptions for:

• java.exe
• installer.jar (Forge file)
• files.minecraftforge.net

Pro tip: Use official Minecraft launcher first to verify.

3️⃣ Update Java & Forge Manually

Download latest Java 21 from Eclipse Adoptium. For Mod Mayhem (1.20.1 recommended):

1. Grab Forge installer from files.minecraftforge.net.
2. Run with: java -jar forge-1.20.1-47.3.0-installer.jar --installServer

4️⃣ Clear Cache & Reinstall

Delete %appdata%\.minecraft\versions and CurseForge cache. Fresh install via Twitch/CurseForge app. For stubborn cases:

• Use MultiMC or Prism Launcher for better error handling.
• Mirror downloads: Search "Forge offline installer" on trusted forums.

5️⃣ Advanced: Edit Installer Args

If all fails, edit installer with JVM args: -Djava.net.preferIPv4Stack=true. Forces IPv4 for stability.
