-# Hytale F2P Server Setup Guide
+# Hytale F2P Server Guide

-## Server File Setup
+Play with friends online! This guide covers both easy in-game hosting and advanced dedicated server setup.

-**Download server file:**
-```
-https://files.hytalef2p.com/server
-```
-
-**Replace the file here:**  
-`<your_path>\HytaleF2P\release\package\game\latest\Server`
-
-If you don't have any custom installation path:
-
-1. Press **WIN + R**  
-2. Type: `%localappdata%\HytaleF2P\release\package\game\latest\Server`  
-3. Press **Enter**
-
-You will be redirected to the correct folder automatically.
-
-## Network Setup - Radmin VPN Required
-
-**Important:** The server only supports third-party software for LAN-style connections. You must use **Radmin VPN** to connect players together.
-
-1. **Download and install [Radmin VPN](https://www.radmin-vpn.com/)**
-2. **Create or join a network** in Radmin VPN
-3. **All players must be connected** to the same Radmin network
-4. **Use the Radmin VPN IP address** to connect to the server
-
-This creates a virtual LAN environment that allows the Hytale server to work properly with multiple players.
-
-## RAM Allocation Guide (Windows)
-
-When you start a Hytale server using `start-server.bat`, Java will use very little memory by default.  
-This can cause slow startup, crashes, or the server not launching at all.
-
-**You should always allocate RAM in your launch command.**
-
-Edit your `start-server.bat` file and use the version that matches your PC:

-### PC with 4 GB RAM
-*Best for small servers / testing*
+## Part 1: Playing with Friends (Online Play)
+
+The easiest way to play with friends - no manual server setup required!
+
+### How It Works
+
+1. **Start the game** via F2P Launcher
+2. **Click "Online Play"** in the main menu
+3. **Share the invite code** with your friends
+4. Friends enter your invite code to join
+
+The game automatically handles networking using UPnP/STUN/NAT traversal.
+
+### Network Requirements
+
+For Online Play to work, you need:
+
+- **UPnP enabled** on your router (most routers have this on by default)
+- **Public IP address** from your ISP (not behind CGNAT)
+
+### Common Issues
+
+#### "NAT Type: Carrier-Grade NAT (CGNAT)" Warning
+
+If you see this message:
+```
+Connected via UPnP
+NAT Type: Carrier-Grade NAT (CGNAT)
+Warning: Your network configuration may prevent other players from connecting.
+```
+
+**What this means:** Your ISP doesn't give you a public IP address. Multiple customers share one public IP, which blocks incoming connections.
+
+**Solutions:**
+
+1. **Contact your ISP** - Request a public/static IP address (may cost extra)
+2. **Use a VPN with port forwarding** - Services like Mullvad, PIA, or AirVPN offer this
+3. **Use Radmin VPN or Playit.gg** - Create a virtual LAN with friends (see below)
+4. **Have a friend with public IP host instead**
+
+#### "UPnP Failed" or "Port Mapping Failed"
+
+**Check your router:**
+1. Log into router admin panel (usually `192.168.1.1` or `192.168.0.1`)
+2. Find UPnP settings (often under "Advanced" or "NAT")
+3. Enable UPnP if disabled
+4. Restart your router
+
+**If UPnP isn't available:**
+- Manually forward **port 5520 UDP** to your computer's local IP
+- See "Port Forwarding" section below
+
+#### "Strict NAT" or "Symmetric NAT"
+
+Some routers have restrictive NAT that blocks peer connections.
+
+**Try:**
+1. Enable "NAT Passthrough" or "NAT Filtering: Open" in router settings
+2. Put your device in router's DMZ (temporary test only)
+3. Use Radmin VPN as workaround
+
+### Workarounds for NAT/CGNAT Issues
+
+#### Option 1: playit.gg (Recommended)
+
+Free tunneling service - only the host needs to install it:
+
+1. **Download [playit.gg](https://playit.gg/)** and run it - Connect your account from the terminal (do not close it when playing on the server)  
+2. **Add a tunnel** - Select "UDP", tunnel description of "Hytale Server", port count `1`, and local port `5520`
+3. **Start the tunnel** - You'll get a public address like `xx-xx.gl.at.ply.gg:5520`
+4. **Share the address** - Friends connect directly using this address
+
+Works with both Online Play and dedicated servers. No software needed for players joining.
+
+#### Option 2: Radmin VPN
+
+Creates a virtual LAN - all players need to install it:
+
+1. **Download [Radmin VPN](https://www.radmin-vpn.com/)** - All players install it
+2. **Create a network** - One person creates, others join with network name/password
+3. **Host via Online Play** - Use your Radmin VPN IP instead
+4. **Friends connect** - They'll see you on the virtual LAN
+
+Both options bypass all NAT/CGNAT issues. But for **Windows machines only!**
+
+#### Option 3: Tailscale
+It creates mesh VPN service that streamlines connecting devices and services securely across different networks. And **works crossplatform!!**
+
+1. All member's are required to download [Tailscale](https://tailscale.com/download) on your device.
+[Once installed, Tailwind starts and live inside your hidden icon section in Windows, Mac and Linux]
+2. Create a **common tailscale** account which will shared among your friends to log in.
+3. Ask your **host to login in to thier tailscale client first**, then the other members.
+##### Host
+  1. Open your singleplayer world
+  2. Go to Online Play settings
+  3. Re-save your settings to generate a new share code
+##### Friends
+  1. Ensure Tailscale is connected
+2. Use the new share code to connect
+[To test your connection, ping the host's ipv4 mentioned in tailwind]
+---
+
+## Part 2: Dedicated Server (Advanced)
+
+For 24/7 servers, custom configurations, or hosting on a VPS/dedicated machine.
+
+### Quick Start
+
+#### Step 1: Get the Server JAR
+
+The server scripts will automatically download the pre-patched server JAR if it's not present.
+
+**Option A:** Let the scripts download automatically (requires `HYTALE_SERVER_URL` to be configured)
+
+**Option B:** Manually place `HytaleServer.jar` (pre-patched for F2P) in the Server directory:
+
+- **Windows:** `%localappdata%\HytaleF2P\release\package\game\latest\Server`
+- **macOS:** `~/Library/Application Support/HytaleF2P/release/package/game/latest/Server`
+- **Linux:** `~/.hytalef2p/release/package/game/latest/Server`
+
+If you have a custom install path, the Server folder is inside your custom location under `HytaleF2P/release/package/game/latest/Server`.
+
+#### Step 2: Run the Server
+
+**Windows:**
+```batch
+cd scripts
+run_server.bat
+```
+
+**macOS / Linux:**
+```bash
+cd scripts
+./run_server.sh
+```
+
+The scripts will:
+1. Find your game installation automatically
+2. Download the pre-patched server JAR if needed
+3. Fetch session tokens from the auth server
+4. Start the server
+
+#### Step 3: Connect Players
+
+Share your server IP address with players. They connect via the F2P Launcher's server browser or direct connect.
+
+---
+
+## Network Setup (Dedicated Server)
+
+### Local Network (LAN)
+
+If all players are on the same network:
+1. Find your local IP: `ipconfig` (Windows) or `ifconfig` (Mac/Linux)
+2. Share this IP with players on your network
+3. Default port is `5520`
+
+### Port Forwarding (Internet Play)
+
+To allow direct internet connections:
+
+1. Forward **port 5520 (UDP)** in your router
+2. Find your public IP at [whatismyip.com](https://whatismyip.com)
+3. Share your public IP with players
+
+**Windows Firewall:**
+```powershell
+# Run as Administrator
+netsh advfirewall firewall add rule name="Hytale Server" dir=in action=allow protocol=UDP localport=5520
+```
+
+---
+
+## Configuration
+
+### Environment Variables
+
+Set these before running to customize your server:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `HYTALE_SERVER_URL` | (placeholder) | URL to download pre-patched server JAR |
+| `HYTALE_AUTH_DOMAIN` | `sanasol.ws` | Auth server domain |
+| `HYTALE_BIND` | `0.0.0.0:5520` | Server IP and port |
+| `HYTALE_AUTH_MODE` | `authenticated` | Auth mode (see below) |
+| `HYTALE_SERVER_NAME` | `My Hytale Server` | Server display name |
+| `HYTALE_GAME_PATH` | (auto-detected) | Override game location |

+
+**Example (Windows):**
+```batch
+set HYTALE_SERVER_NAME=My Awesome Server
+set JVM_XMX=8G
+run_server.bat
+```
+
+**Example (Linux/macOS):**
+```bash
+HYTALE_SERVER_NAME="My Awesome Server" JVM_XMX=8G ./run_server.sh
+```
+
+### Authentication Modes
+
+| Mode | Description | Use Case |
+|------|-------------|----------|
+| `authenticated` | Players log in via F2P Launcher | Public servers |
+| `unauthenticated` | No login required | LAN parties, testing |
+| `singleplayer` | Local play only | Solo testing |
+
+---
+
+## RAM Allocation Guide
+
+Adjust memory based on your system:
+
+| System RAM | Players | JVM_XMS | JVM_XMX |
+|------------|---------|---------|---------|
+| 4 GB | 1-3 | `512M` | `2G` |
+| 8 GB | 3-8 | `1G` | `4G` |
+| 16 GB | 8-15 | `2G` | `8G` |
+| 32 GB | 15+ | `4G` | `12G` |
+
+**Example for large server:**
+```bash
+JVM_XMS=4G JVM_XMX=12G ./run_server.sh
+```
+
+**Tips:**
+- `-Xms` = minimum RAM (allocated at startup)
+- `-Xmx` = maximum RAM (upper limit)
+- Never allocate all your system RAM - leave room for OS
+- Start conservative and increase if needed
+
+---
+
+## Server Commands
+
+Once running, use these commands in the console:
+
+| Command | Description |

+| `help` | Show all commands |
+| `stop` | Stop server gracefully |
+| `save` | Force world save |
+| `list` | List online players |
+| `op <player>` | Give operator status |
+| `deop <player>` | Remove operator status |
+| `kick <player>` | Kick a player |
+| `ban <player>` | Ban a player |
+| `unban <player>` | Unban a player |

+./run_server.sh [OPTIONS]
 ```

- Uses up to **2 GB**
- Leaves enough memory for Windows
+| Option | Description |
+|--------|-------------|
+| `--bind <ip:port>` | Server address (default: 0.0.0.0:5520) |
+| `--auth-mode <mode>` | Authentication mode |

 ```

- Uses up to **4 GB**
- Stable for most setups
+### Manual Backup
+
+1. Use `save` command or stop the server
+2. Copy the `universe/` folder
+3. Store in a safe location
+
+### Restore
+
+1. Stop the server
+2. Delete/rename current `universe/`
+3. Copy backup to `universe/`
+4. Restart server

-### PC with 16 GB RAM
-*Perfect for large or modded servers*
+## Troubleshooting
+
+### "Java not found" or "Java version too old"
+
+**Java 21 is REQUIRED** (the server uses class file version 65.0).
+
+**Install Java 21:**
+- **Windows:** `winget install EclipseAdoptium.Temurin.21.JDK`
+- **macOS:** `brew install openjdk@21`
+- **Ubuntu:** `sudo apt install openjdk-21-jdk`
+- **Fedora:** `sudo dnf install java-21-openjdk`
+- **Arch:** `sudo pacman -S jdk21-openjdk`
+- **Download:** [adoptium.net/temurin/releases/?version=21](https://adoptium.net/temurin/releases/?version=21)
+
+**macOS: Set Java 21 as default:**
+```bash
+export JAVA_HOME=$(/usr/libexec/java_home -v 21)
+export PATH="$JAVA_HOME/bin:$PATH"
+```
+Add these lines to `~/.zshrc` or `~/.bash_profile` to make permanent.
+
+### "Game directory not found"
+
+- Download game via F2P Launcher first
+- Or set `HYTALE_GAME_PATH` environment variable
+- Check custom install path in launcher settings
+
+### "Assets.zip not found"
+
+Game files incomplete. Re-download via the launcher.
+
+### "Port already in use"

 ```bash
-java -Xms2G -Xmx8G -jar HytaleServer.jar --assets ..\Assets.zip
+./run_server.sh --bind 0.0.0.0:5521
 ```

- Uses up to **8 GB**
- Ideal for heavy worlds and plugins
+### "Out of memory"
+
+Increase JVM_XMX:
+```bash
+JVM_XMX=6G ./run_server.sh
+```
+
+### Players can't connect
+
+1. Server shows "Server Ready"?
+2. Using F2P Launcher (not official)?
+3. Port 5520 open in firewall?
+4. Port forwarding configured (for internet)?
+5. Try `--auth-mode unauthenticated` for testing
+
+### "Authentication failed"
+
+- Ensure players use F2P Launcher
+- Auth server may be temporarily down
+- Test with `--auth-mode unauthenticated`

 ---

-## Tips
+## Docker Deployment (Advanced)

- `-Xms` = minimum RAM allocation
- `-Xmx` = maximum RAM allocation  
- **Never allocate all your system RAM** — Windows still needs memory to run
- **Test your configuration** with a small world first
- **Monitor server performance** and adjust RAM as needed
+For production servers, use Docker:

+```bash
+docker run -d \
+  --name hytale-server \
+  -p 5520:5520/udp \
+  -v ./data:/data \
+  -e HYTALE_AUTH_DOMAIN=sanasol.ws \
+  -e HYTALE_SERVER_NAME="My Server" \
+  -e JVM_XMX=8G \
+  ghcr.io/hybrowse/hytale-server-docker:latest
+```

+See [Docker documentation](https://github.com/Hybrowse/hytale-server-docker) for details.
+
+---
+
+## Server Settings Summary
+
+### Minimal Setup
+```bash
+./run_server.sh
+```
+
+### Custom Memory
+```bash
+JVM_XMS=2G JVM_XMX=8G ./run_server.sh
+```
+
+### Custom Port
+```bash
+HYTALE_BIND=0.0.0.0:25565 ./run_server.sh

Rahul-Sahani04	64892c81e9	Profile System & Mod Loading Fixes Added a full profile system and fixed a few critical mod loading issues. What changed Profiles — Implemented proper profile management (create, switch, delete). Each profile now has its own isolated mod list. Mod Isolation — Fixed ModManager so mods are strictly scoped to the active profile. Browsing and installing only affects the selected profile. Critical Fix — Fixed a path bug where mods were being saved to ~/AppData/Local on macOS (Windows path) instead of ~/Library/Application Support. Mods now save to the correct location and load correctly in-game. Stability — Added an auto-sync step before every launch to make sure the physical mods folder always matches the active profile. UI — Added a profile selector dropdown and a profile management modal.	2026-01-20 11:52:36 +05:30
