How Does IsHyUp Work?
IsHyUp checks if a Hytale server is online by performing two types of checks:
- Protocol Check: We attempt to establish a connection using the official Hytale protocol. This tells us if the server is running a genuine Hytale server, instead of other games like Minecraft.
- Host Ping: We perform a simple network ping to check if the host machine is reachable on the network.
When you enter a server address, our system resolves the domain to an IP address, connects to the default Hytale port (5520), and attempts to communicate using the Hytale protocol.
What Do the Server Statuses Mean?
This means the server responded with a valid Hytale protocol response. The server is running genuine Hytale server software and is accepting connections. This is a verified Hytale server.
The port is open and something is listening, but it did not respond with a valid Hytale protocol. This could mean:
- A different game server is running on that port
- A web server or other service is using the port
- The server software is not Hytale
- The Hytale server is still starting up
The server could not be reached. This could mean:
- The server is not running
- The port is not open or is blocked by a firewall
- The domain/IP address is incorrect
- Network issues between our servers and the target
- The server crashed or is being restarted
What is the Hytale Protocol Check?
The Hytale Protocol check attempts to communicate with the server using Hytale's native communication protocol. This is the same protocol that the Hytale game client uses to connect to servers.
Protocol Status Meanings:
- ✓ Verified - The server responded with a valid Hytale protocol packet. This confirms it's running Hytale server software.
- ⚠ Port Open (Not Hytale) - Something is listening on the port, but it's not responding with Hytale protocol.
- ✗ Not Responding - The port is closed or the connection was refused/timed out.
The protocol version shown (if available) indicates which version of Hytale the server is running.
What is Host Ping?
Host Ping is a basic network reachability check using TCP. It tells you whether the machine (host) at the given address is reachable over the network.
Host Ping vs Protocol Check:
| Scenario | Host Ping | Protocol | Meaning |
|---|---|---|---|
| Hytale server running | ✓ | ✓ | Everything is working! |
| Different server on port | ✓ | ⚠ | Host is up, but not Hytale |
| Host up, port closed | ✓ | ✗ | Machine online, Hytale not running |
| Host unreachable | ✗ | ✗ | Server is completely offline |
What Does Latency Mean?
Latency (measured in milliseconds, ms) is the time it takes for data to travel from our server to the Hytale server and back. Lower latency means faster response times.
Latency Guide:
- < 50ms Excellent
- 50-100ms Good
- 100-200ms Acceptable
- 200-300ms High
- > 300ms Very High
Note: The latency shown is from our servers, not from your location. Your actual in-game latency may differ.
What Port Does Hytale Use?
The default Hytale server port is 5520. If no port is specified in the address, we automatically check this port.
You can specify a custom port by adding it after the address with a colon:
# Default port (5520)
play.example.com
# Custom port
play.example.com:25565
What is "Resolved IP"?
When you enter a domain name (like play.example.com), our system needs to convert it to an IP address to connect. The Resolved IP shows what IP address the domain name points to.
If you see "Could not resolve", it means:
- The domain name doesn't exist
- There's a typo in the address
- DNS servers couldn't find the domain
Common Questions
Why does my server show as offline when it's running?
Common causes include: firewall blocking port 5520, incorrect port forwarding, the server still starting up, or network issues. Make sure the port is properly forwarded and not blocked.
Can I check my own server?
Yes! Enter your server's public IP or domain name. Note that you cannot use localhost or 127.0.0.1 as we check from our servers, not your machine.
How accurate is the status check?
Our checks are real-time and very accurate. However, server status can change rapidly. If a server just went online or offline, it may take a moment for our check to reflect the new status.
What does "QUIC" or "TCP" mean in errors?
These are network protocols. QUIC is a modern protocol that Hytale may use for faster connections, while TCP is the traditional protocol. If you see errors for either, it indicates connection issues at that protocol level.
