Hytale server firewall and port basics
Players reach your server through a port, which is like a numbered door on the machine. If the door is closed by a firewall or router, nobody can get in. Confirm all details in the official Hytale server documentation.
What sources report
Community guides based on the official manual say the Hytale server listens on port 5520 by default and uses QUIC over UDP, not TCP. They also say you can change the port with a bind option at launch. Because Hytale is changing, verify this before opening anything.
TCP versus UDP
TCP and UDP are different protocols. A rule that opens TCP 5520 does not open UDP 5520. For a UDP game, create a UDP rule. Many port mistakes come from picking the wrong one.
If you host on a hosting panel
The host assigns the port and handles network rules. Use the address and port shown in your panel. Tabi Cloud servers also include DDoS protection.
If you self-host
- Find your server machine's local IP address.
- Allow the UDP port in the operating system firewall.
- Log into your router and forward the UDP port to that local IP.
- Give the machine a fixed local address so the rule keeps working.
- Share your public IP or a domain with players.
- Test from a different network, such as a phone hotspot.
Security tips
- Open only the ports you need.
- Do not expose admin tools to the internet.
- Keep Java and server files updated.
- Use a whitelist for private worlds.
Changing the port
If you change the default, update your firewall rule and tell players to include the port in the address.
