Windows Issues

"Failed to connect to server" / Server won't boot

Symptoms: Singleplayer world fails to load, "Server failed to boot" error.

Solution - Whitelist in Windows Firewall:

1. Open Windows Settings > Privacy & Security > Windows Security
2. Click Firewall & network protection > Allow an app through firewall
3. Click Change settings
4. Find HytaleClient.exe and check both Private and Public
5. If not listed, click Allow another app and browse to:

   %localappdata%\HytaleF2P\release\package\game\latest\Client\HytaleClient.exe
   

Duplicate mod error

Symptoms: java.lang.IllegalArgumentException: Tried to load duplicate plugin

Solution:

1. Navigate to your mods folder:

   %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods
   

2. Remove any duplicate .jar files
3. Restart the launcher

SmartScreen blocks the launcher

Solution:

1. Click More info
2. Click Run anyway

Linux Issues

GPU not detected / Using software rendering (llvmpipe)

Symptoms:

• Game uses integrated GPU instead of dedicated GPU
• Very low FPS / unplayable performance
• Play button not clickable
• Log shows llvmpipe instead of your GPU

Solution for NVIDIA:

__EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json ./HytaleF2P.AppImage

Solution for AMD (hybrid GPU systems):

DRI_PRIME=1 ./HytaleF2P.AppImage

Permanent fix - Create a launcher script:

#!/bin/bash
export __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json
export DRI_PRIME=1
./HytaleF2P.AppImage

Note: On some desktop systems with AMD iGPU + dGPU, the GPU selector may be inverted (selecting iGPU actually uses dGPU). Use whichever option works.

SDL3_image / libpng errors

Symptoms:

• DllNotFoundException: Unable to load shared library 'SDL3_image'
• libpng related errors
• Game crashes on startup

Solution - Install dependencies:

Fedora / RHEL:

sudo dnf install libpng libpng-devel

Debian / Ubuntu:

sudo apt install libpng16-16 libpng-dev libgdiplus libc6-dev

Arch Linux:

sudo pacman -S libpng

Alternative - Replace corrupted library:

cd ~/.hytalef2p/release/package/game/latest/Client/
mv libSDL3_image.so libSDL3_image.so.bak
wget https://github.com/user-attachments/files/24710966/libSDL3_image.zip
unzip libSDL3_image.zip
chmod 644 libSDL3_image.so
rm libSDL3_image.zip

AppImage won't launch / FUSE error

Solution:

# Debian/Ubuntu
sudo apt install libfuse2

# Fedora
sudo dnf install fuse

# Arch
sudo pacman -S fuse2

Missing libxcrypt.so.1

Solution:

# Fedora/RHEL
sudo dnf install libxcrypt-compat

# Arch
sudo pacman -S libxcrypt-compat

Wayland display issues

Symptoms: Game doesn't launch, stuck at loading, or display glitches on Wayland.

Solution - Force X11:

GDK_BACKEND=x11 ./HytaleF2P.AppImage

Alternative - Electron Wayland hint:

ELECTRON_OZONE_PLATFORM_HINT=auto ./HytaleF2P.AppImage

Steam Deck / Gamescope issues

Solution 1 - Add custom launch options in Steam:

ELECTRON_OZONE_PLATFORM_HINT=x11 %command%

Solution 2 - Launch from Desktop Mode instead of Game Mode.

Solution 3 - Force X11:

GDK_BACKEND=x11 ./HytaleF2P.AppImage

Ubuntu LTS-based distros (Linux Mint, Zorin OS, Pop!_OS)

These distributions may have compatibility issues due to older system packages. This is a limitation of the Hytale game client, not the launcher.

Workarounds:

1. Install all dependencies listed above
2. Try the SDL3_image replacement
3. Consider using a more recent distribution or Flatpak/AppImage with bundled dependencies

---

macOS Issues

"Butler system error -86" (Apple Silicon)

Symptoms: Butler execution failed: spawn Unknown system error -86 (EXC_BAD_CPU_TYPE)

Cause: Butler (the update tool) is x86_64 only.

Solution - Install Rosetta 2:

softwareupdate --install-rosetta

Then restart the launcher.

Auto-update fails with code signature error

Symptoms:

Code signature at URL did not pass validation
domain: 'SQRLCodeSignatureErrorDomain'

Solution - Manual update:

1. Download the latest version manually from Releases
2. Backup your data first (see Backup Locations)
3. Install the fresh download

"Unidentified developer" warning

Solution:

1. Open System Settings > Privacy & Security
2. Scroll to Security section
3. Find the message about "Hytale F2P Launcher"
4. Click Open Anyway
5. Authenticate and click Open

App won't open (quarantine)

Solution:

xattr -rd com.apple.quarantine /Applications/Hytale-F2P-Launcher.app

Connection & Server Issues

"Failed to connect to server" in Singleplayer

Possible causes:

1. Windows Firewall blocking (see Windows section)
2. Patched server JAR download failed
3. Regional network restrictions

Solution - Check patched JAR:

1. Look for HytaleServer.jar in:
   • Windows: %localappdata%\HytaleF2P\release\package\game\latest\Server\
   • Linux: ~/.hytalef2p/release/package/game/latest/Server/
   • macOS: ~/Library/Application Support/HytaleF2P/release/package/game/latest/Server/
2. If missing or very small, the download may have failed

Solution - Regional restrictions:

Some countries (Russia, Turkey, Indonesia, etc.) may have issues accessing download servers.

• Try using a VPN for the initial download
• Once downloaded, the patched JAR is cached locally

"Infinite Booting Server" / Server stuck loading

Solution:

1. Check if the patched JAR downloaded successfully (see above)
2. Ensure your GPU meets minimum requirements
3. Check launcher logs for specific errors
4. Try with a VPN if in a restricted region

"Connection timed out from inactivity"

This is expected behavior. Sessions have a 10-hour TTL and will timeout after extended inactivity. Simply reconnect to continue playing.

---

Authentication & Token Issues

"Invalid identity token" / "Failed to start Hytale"

Solution:

1. Restart the launcher - This fetches fresh tokens
2. Check system time - JWT validation requires accurate system time
3. Clear cached tokens:
   • Delete config.json from your HytaleF2P folder
   • Restart the launcher
   • Re-enter your username

Locations:

• Windows: %localappdata%\HytaleF2P\config.json
• Linux: ~/.hytalef2p/config.json
• macOS: ~/Library/Application Support/HytaleF2P/config.json

Token refresh errors

If you see issuer mismatch errors in logs:

1. Delete config.json and player_id.json
2. Restart the launcher
3. This forces a fresh authentication

---

Avatar & Cosmetics Issues

Avatar/skin changes not saving

This is a known F2P limitation:

• F2P mode has no password protection for usernames
• Anyone can use any username
• Cosmetics are stored server-side by username
• If someone else uses your username, they can change your cosmetics

Workaround: Use a unique username that others are unlikely to choose.

Character invisible / Customization crashes

Solution:

1. Use Repair Game in launcher Settings
2. Verify Assets.zip exists in your game folder
3. Clear cached assets:
   • Windows: Delete %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\CachedAssets\
4. Restart the launcher

Avatar creator shows "Offline Mode"

Cause: Cannot connect to auth server.

Solution:

1. Check your internet connection
2. Test connectivity: Open https://auth.sanasol.ws/health in browser (should show "OK")
3. Check if firewall is blocking the connection
4. Try disabling VPN (or enabling one if in restricted region)

---

General Issues

Mods not showing up

Solution:

1. Ensure mods are placed in the correct folder:
   • Windows: %localappdata%\HytaleF2P\release\package\game\latest\Client\UserData\Mods\
   • Linux: ~/.hytalef2p/release/package/game/latest/Client/UserData/Mods/
   • macOS: ~/Library/Application Support/HytaleF2P/release/package/game/latest/Client/UserData/Mods/
2. Verify mod files are .jar format
3. Check launcher logs for mod loading errors

Game updates delete configurations/mods

This is a known issue being worked on.

Prevention - Always backup before updating:

• Server configs and worlds
• Mods folder
• config.json and player_id.json

See Backup Locations below.

Play button not clickable

Usually caused by GPU detection failure. See GPU not detected.

Alternative:

1. Go to Settings > Graphics
2. Manually select your GPU
3. Restart the launcher

Read timeout errors

Cause: Network connectivity issues.

Solutions:

1. Check your internet connection stability
2. Try using a VPN
3. Check firewall settings
4. Try at a different time (server load varies)

---

Known Limitations

Linux ARM64 not supported

Hytale does not provide ARM64 game client builds. The launcher downloads from official Hytale servers which only provide:

• Windows x64
• macOS (Universal/Intel)
• Linux x64

This is outside our control.

F2P Username System

• No password protection for usernames
• Anyone can claim any username
• Cosmetics shared by username
• UUIDs generated based on username

A per-player password system is planned for future versions.

Session Timeout

Game sessions have a 10-hour TTL. This is by design for security.
