Connect to your server

To connect to your server, copy the server address and enter it in your Minecraft client, as a new server or with “Direct Connect”. You can find the server address on the server page.

This address includes your server port if “Cracked” is enabled in the options. Read more details about cracked launchers, especially TLauncher, here.

Please make sure that your server is online if you have problems connecting to your server. The status on the server page should be green and be labelled with “Online”. Also, try to refresh the page, and verify again that your server is online.

Try the DynIP

The DynIP is an alternative IP address for your server that helps you to directly connect to your server. Unlike the regular IP, the DynIP changes every time you start your server. To view the DynIP, click on the “Connect” button (i icon when using bedrock or pocketmine) on the server page while your server is online. Copy it and use enter it as the ip to connect to your server.

Why do I need the DynIP?

The Domain Name System

To explain this, you have to understand the Domain Name System (DNS). Every machine connected to the internet has an IP address composed of different numbers. Because humans are not really good at remembering numbers some smart guys invented a system to give names to these numbers, the Domain Name System. Every time you enter a domain, e.g. in your browser or in your Minecraft client, your computer looks this name up and finds the numbers behind this name to connect to the server. To look up the domain name, your computer asks a DNS server, e.g. at Google. If this DNS server doesn't know the IP address behind the name, it then asks the next DNS server, e.g. our DNS server, which knows the correct IP address. Every DNS server and even your computer save the IP addresses behind domain names for a short time to avoid unnecessary requests to other DNS servers. This is called “caching”. Some servers have a caching time that is too long.

DNS & Aternos

Aternos has a highly dynamic system to ensure the best possible use of our limited resources. Because of this, your server starts always on a different machine with a different IP address and port than before. To make it easy for you to connect to your server without entering a different server IP every time, we automatically create and manage a domain name for your server (e.g. With every start, this domain name gets updated and points to a different IP address and a different port. Your computer looks this up for you like explained above. But if a server has a long caching time, the IP address and the port are not updated yet and you try to connect to a wrong IP address, which doesn't work. The DynIP lets you directly connect to the correct IP address and port, but because this changes with every start, using it can be pretty annoying.

How can you fix this?

Flush your DNS cache

A temporary fix would be to temporary flush your DNS cache, so your computer forgets about all cached IP addresses behind the domain names. This doesn't help if a DNS server has a long caching time and it also only helps once.

Change your DNS server

To permanently fix this problem, you can change your DNS server, which is the first DNS server that your computer uses to look up domain names. You can use any public DNS server that you want, we recommend to use the Google Public DNS because it's reliable and fast.

If you are having connection problems on your phone, you can use the Cloudflare DNS app to easily change the DNS server, which is also more secure and faster.
