Just enter an address and port to see the status

Want to know whether a Minecraft server is online right now, how many players are on, and how high the ping is? The free Monitor-only mode in TopoBlocks is all you need: just enter the server’s address and port, and it will query and display:

  • Online status—whether the server is reachable right now.
  • Version—the game version the server reports publicly.
  • Player count—current/maximum players.
  • Ping—the round-trip latency from the query end to the server.

How do you fill in the port? Java Edition defaults to 25565, and Bedrock defaults to 19132; if the operator changed the port, use the actual value from the config. The whole process is read-only—monitoring doesn’t read your world directory and has no write access, and it needs no SSH, RCON, or any account credentials. To learn how to get yourself and your friends connected once you have the address and port, see Connect to a Minecraft Server.

How to read the status: troubleshoot in order when it shows offline

Each reading in the monitor has a specific meaning: high ping is usually caused by network routing or the server being in a different region, and isn’t necessarily related to the server’s own load; once player count hits the cap, new players may not be able to join; and when the version doesn’t match, the client will simply fail to connect. To be clear about the limits: this is a capability built for lightweight personal self-checks, not an enterprise multi-node monitoring platform, and more complex batch monitoring is out of scope right now—we won’t pretend it can do that.

If monitoring shows the server is offline or unreachable, troubleshoot in this order: are the address and port correct → is the edition (Java/Bedrock) selected correctly → is the server actually running → is the firewall or port forwarding letting traffic through. For detailed steps, see Troubleshoot a Server Showing Offline / Unreachable.

Beyond monitoring: full management requires your explicit authorization

Monitor-only mode is always free, read-only, and credential-free. If you also want to do things that change the server—like remote snapshots, recoverability checks, safe deploys, and operation logs—that falls under full management (paid features), and it requires your explicit authorization before anything runs—monitoring itself will never overstep to touch your world. For paid features, prices are shown in the app, and a paid task is automatically refunded if it fails.

If you don’t have your own server yet and want to spin one up before monitoring it, you can use TopoBlocks to launch a server from your phone in one tap (pick the edition/plan/region, with automatic provisioning, no terminal needed); see How to Host a Minecraft Server From Your Phone for details.
