Minecraft Port Checker
Players cannot join if your port is not reachable. This runs a TCP test from our server to yours — the same check your router port forward must pass.
TCP check from our server to yours. Open = something is listening on that port. Closed usually means firewall, no port forward, or the service is down.
Port forwarding troubleshooting
If closed: verify server running, correct server-port, TCP forwarded on router, firewall allows inbound, testing public IP not localhost. Hosting panels may use a different hostname than your domain.
Ports Minecraft server owners need open
| Port | Protocol | Service |
|---|---|---|
| 25565 | TCP | Java Edition gameplay |
| 25575 | TCP | RCON remote console |
| 8192 | TCP | Votifier / NuVotifier votes |
| 19132 | UDP | Bedrock (not tested here) |
| 25566+ | TCP | Additional Java servers on same host |
Port open vs server online
Port open only confirms something listens on TCP. The server status checker runs the actual Minecraft ping protocol — online/offline, player count, MOTD, version. Use both when debugging connectivity.
How to use this tool
- 1
Enter your public hostname or IP
Use the IP or domain players connect with — not 127.0.0.1 unless testing locally. For home servers use your public IP from whatismyip.com.
- 2
Select the correct port
25565 for Java Edition, 8192 for Votifier, 25575 for RCON. Click a preset or type a custom port for proxy backends.

Run the check and interpret results
Open means TCP connected — something is listening. Closed means firewall, no port forward, or service down. If open but players cannot join, use the server status checker next.
Frequently asked questions
What port does Minecraft Java Edition use?
Default Java Edition port is 25565 TCP. Multiple servers on one machine need unique ports in server.properties server-port=.
What does port open mean for a Minecraft server?
Open means a TCP connection succeeded — something accepts connections on that port. Closed means nothing responded: firewall, wrong forward, server offline, or wrong port.
How do I port forward for Minecraft?
Router Port Forwarding: external 25565 → internal 25565 TCP → server LAN IP. Set static DHCP for the server machine. Test with this tool using your public IP.
What port does Minecraft Bedrock use?
Bedrock defaults to UDP 19132. This checker tests TCP only — Java 25565, Votifier 8192, RCON 25575.
Port is open but players still cannot connect?
TCP open confirms something listens — not necessarily Minecraft protocol. Use the server status checker. Also verify online-mode, server fully started, and server-ip is blank in server.properties.
Why check Votifier port 8192?
Votifier listens separately for vote notifications. If 25565 is open but 8192 closed, players join but votes fail. Forward both ports.
Does this work behind Cloudflare?
Cloudflare proxies HTTP/HTTPS only, not Minecraft TCP 25565. Do not orange-cloud your game server hostname. Connect directly to your server IP or a non-proxied DNS record.
Can I check ports on a hosting panel server?
Yes — use the hostname or IP your host provides in the allocation panel. Shared hosts often handle forwarding; closed results may mean the server process is stopped.
