Aternos: How to create a Minecraft server free of charge

On page 10 sections

Briefly

A free server that works as long as people play on it

Aternos - free hosting: the server is running, while someone is playing it, and the empty one turns itself off. Register at aternos.org, create a Java Edition server, click start and give your friends an address like имя.aternos.me.

How to create a server

Open the aternos.org and register: name and password or entry through Google. The mail is tied - it comes with a warning before removing the server.
Create a server and select an edition: Java Edition - for regular Minecraft on a computer, Bedrock - for phones and consoles.
Set the name and description that players will see in the server list.
Click start and accept the Minecraft License Agreement (EULA). If there is not enough capacity, the server will queue.
When the status turns green, the server is running. His address is written on the server page.

The game version, kernel (Paper, Fabric, Forge) and mod modpacks are selected there, in the server sections. How kernels differ from each other - in the guides “How to install plugins” and “How to install mods”.

How to log into the server

Copy the server address from the Aternos page - like имя.aternos.me.
In the game, "Netgame" () "Add" () () "Adress server") insert an address. Or "at the address" to come in once.
Give your friends the same address. The server must be running - if it is turned off, it will not respond.

The server runs on a different Aternos machine each time, so the port changes. It is stored in the address entry имя.aternos.me, and the Java version of the game finds the port itself. In Bedrock, you enter the port manually - it is on the server page.

Which is limited

What	Like on Aternos
Queue	When there is not enough capacity, the launch gets queued. The turn has come - confirm the launch, otherwise the place will be lost.
Empty server	It turns off on its own: while there is no one on it, the timer runs. As long as at least one person is playing, the server operates without a time limit.
Memory	Each core and version has a vanilla of 1.20.1 to 2,400 MB. Paper is faster than a vanilla server in the same memory.
Your own world	Loaded by .zip or a folder with level.dat, up to 1 GB.
Plugins and mods	Only from the Aternos catalog - you cannot load your own .jar file. Builds - from CurseForge and Modrinth.
Port	One per server: Geyser for Bedrock and voice chat will not work together - both need their own UDP port.
Disposal	A server that hasn't been running for about three months is removed. It's enough to press launch sometimes.

Aternos prohibits keeping the server turned on by bots: it finds and turns off such servers, and can block the account.

Without a license

By default, the server only allows the license - like any server with online-mode=True. To allow without it, the server settings include "Cracked". The Aternos themselves are warned: without checking, anyone goes in under a stranger's nickname, so they advise the password entry plague, such as AuthMe Reloaded.

"Cracked" better turn it on at once. Switch it to a server where you've already played -- the players' things and places, the list of operators and the white list are likely to go missing: the server will start to recognize the players differently.

From TLauncher Aternos is often not available: this launcher does not read a record of Aternos storing the port. Write an address along with the port via a colon — the port is shown on the server page.

If you're in Russia

Aternos lives on the commercial and asks that the blockers be turned off. In Russia, advertising often does not load because of the service provider's blocking, and the website takes it for a blocker. The Aternos himself writes about it in the certificate directly and he doesn't want to change anything. If the site doesn't allow the server to start up, they stay with their server or are ready, down below.

If it doesn't work

The server is down. The status on the Aternos page should be green; after launching, refresh the page.
Error the first time. Often it helps to simply connect again.
The address is "outdated". The computer remembers the server's last address. Aternos gives the second -- DynIP: it's shown on the server page button and it changes at each launch.
"It was not possible to check the user name!" - the player does not have a license, and “Cracked” is turned off. More details - It's a wiki mistake..

All login error texts and what they mean are in the section "Errors". You can check if the server is responding in "Search Check".

When you need another server

The farm must work without you or friends log in at different times - the empty server on Aternos is turned off. You need a server on your computer or paid hosting: “How to create a server”.
Play together now - it’s easier to open the world online or play via Radmin VPN.
You need a company, not your own server - ready-made servers with live online Monitoring.
