Hytale Port Forwarding and Firewall Fix
Hytale uses QUIC over UDP. If UDP 5520 is blocked, players will time out or the server will not appear in the browser.
Required Ports
| Port | Protocol | Purpose |
|---|---|---|
| 5520 | UDP | Game traffic (QUIC) |
Step-by-Step Fix
- Forward UDP 5520 on your router to the server's local IP.
- Allow UDP 5520 in your firewall.
- Bind to all interfaces using
--bind 0.0.0.0:5520. - Test connection from an external network with
your.ip.address:5520.
Firewall Examples
# Windows
New-NetFirewallRule -DisplayName "Hytale Server" -Direction Inbound -Protocol UDP -LocalPort 5520 -Action Allow
# Linux (UFW)
sudo ufw allow 5520/udp
Note: Opening TCP 5520 is not enough. Hytale traffic is UDP only.
