Minecraft server guides
Connection errors, player counts, ping, and keeping a server visible to the people trying to join it.
Java vs Bedrock: why you can't connect to a Minecraft server
Minecraft says the server is unreachable but your friend is on it right now? Java and Bedrock are two different games with different protocols, ports, and addresses — here's how to tell which side you're on.
MOTD, player count, ping: how Minecraft server status actually works
Where the server list gets its MOTD, player count, and latency from — the Server List Ping protocol, what it can and can't tell you, and why the player count is sometimes a lie.
Why your Minecraft server dropped off server lists (and how to get back)
Server-list sites mark you offline or quietly delist you when their crawlers can't ping you. The usual causes — restart windows, DDoS filters, moved hosts, dead SRV records — and how to catch it before your traffic dies.
Server lists say your Minecraft server is offline, but you can join it fine
Your server accepts connections but every tracker shows it offline. That gap is the difference between a login handshake and a Server List Ping, and the fix depends on which one is failing.
Minecraft connection errors decoded: io.netty, timed out, refused, and the rest
What io.netty.channel.AbstractChannel$AnnotatedConnectException, Connection refused, Failed to login, and Timed out actually mean, and which of them are your problem to fix.
Server lag or server downtime? How to tell the difference before you restart
Players say the server is down. It's pinging fine. Lag and downtime look identical from the player's side and need opposite responses, here's how to separate them with evidence.
Give your Minecraft community a status page instead of a Discord ping
When your server goes down, everyone asks at once. A public status page answers before they ask, and gives you a record of what actually happened.
Your Minecraft server says 0/0 players. Here's what's actually happening.
If your server pings as online but reports zero players when you know there are people on it, the cause is almost always one of four protocol-level quirks. Here's how to tell which.
How to check if a Minecraft server is online (without launching the game)
Hypixel, 2b2t, EarthMC, and the rest, a quick guide to telling whether a server is actually offline, just queueing you, or whether the problem is on your end.
