What is error$annotatedconnectexception on Minecraft?

It can be overwhelming when you receive the error notification “Minecraft$annotatedconnectexception: Connection Refused.” 

This connection error simply means that you weren’t able to connect successfully with your chosen Minecraft server. This may be due to a failed request or the signal may have been cut off.

Connection errors can also cause the Minecraft LAN to stop working.

What causes Minecraft connection error?

Before we solve the issue, it’s important to understand the possible causes of connection failure:

  • IP address issue: There are two possible causes of IP issues –– the wrong IP address or the wrong port may have been listed. Both the IP address and port are important because they are used to connect with the appropriate server. Unless you’re using a static IP address, you need to check the IP address assigned to you by your ISP.
  • Outdated Java software: If you’ve been playing Minecraft for a while, you’d know that it requires the latest version of Java to work properly. If your Java is outdated, expect to receive many error notifications, including the failed connection error.
  • Firewall: There are also times when your PC Firewall may be blocking your connection to the server. Your Java files and Minecraft game directory need to bypass the Firewall to work properly to fix this error.
  • Incompatible game software: There are also times when installed software on your PC or laptop causes incompatibility issues with Minecraft. To fix this issue, make sure to check online for a full list of incompatible software, such as antiviruses, parental control software, and malware or adware. You will need to uninstall these programs and restart your computer.

If the connection between the Minecraft server and the client is disrupted then you may also experience the “Failed to Synchronize Registry Data From Server” error.

Do a Powercycle

As mentioned, the easiest way to fix this issue is to do a simple power cycle. A powercycle involves restarting Minecraft, restarting your computer, and restarting your router.

  • Close Minecraft and turn off your computer.
  • Disconnect your router from the power supply.
  • Wait five minutes before restarting your PC and plugging in your internet router.
  • Launch Minecraft and check if the issue persists.


Reset your network configurations

If the above solution doesn’t work, the problem might be with your network settings. 

Here’s how to reset network configurations:

  • Search for Command Prompt in the Windows search bar then “Run as Administrator.”
  • Type the following commands:

ipconfig /flushdns

ipconfig /release

ipconfig /renew

netsh winsock reset

netsh int ip reset

  • Restart your PC and check if the issue persists.


Enter the IP address and port

If you don’t have a static IP address, this means that your IP will change every time your connection is reset. Because of this, you need to check that your IP address and port are correct before adding them to the Minecraft Launcher:

  • Search for Command Prompt in the Windows search bar, then “Run as Administrator.”
  • Type ipconfig and take note of the IPV4 address.
  • Navigate the folders Minecraft Servers folder > Maxwell > MinecraftServer. Open the Server Properties text document. Check the number under Server Port.
  • Launch Minecraft and navigate to Play Multiplayer.
  • Select your chosen Server and click Edit. Enter the IPV4 address and the Server Port you noted earlier. Click Done.
  • Restart your PC and check if the issue persists.


Get firewall permissions (when using your own or someone else’s server)

When using someone else’s server or your own server, a common cause of Minecraft connection issues is that the server is blocked by a Firewall. 

Here’s how to change firewall permissions:

  • Search for Windows Security in the Windows search bar
  • Select Firewall & Network protection, then click Allow an app through Firewall.
  • On the next page, select Change settings. Click Yes when a warning prompt appears.
  • Scroll down the window, and under Allow another App, click Browse. Open the folder where Minecraft is installed.
  • Select Minecraft Launcher and click Open.
  • Click Browse again and look for your MinecraftServer folder. 
  • Still, on the Change Settings page, check that all files with the Java label are allowed. Look for Java Platform SE binary and allow Private and Public connections to the server.
  • Restart Minecraft and check if the issue persists.

Files being blocked by your firewall can also cause Minecraft Failed to Download the File, the File Contents Differ From What Was Expected (jna-4.4.0.jar Error). So it is worth getting the settings right.


Portforward your network100

Portforwarding your network is another effective solution if you have problems with your own server.

  • Access your WiFi router settings by entering your username and password.
  • Navigate to the Port Forwarding tab > Virtual Server > Advanced,
  • You should open a page where you can enter your Device name, port, and IP address. Fill in these information based on your computer settings.
  • You will also have to choose a Protocol. These are usually TCP/UDP or both. 
  • Click Apply or Save.
  • Restart Minecraft and check if the issue persists.


Check your ISP network access

If the above solutions don’t work, your internet access may be blocked by your internet service provider (ISP). The only way to solve this issue is to contact your ISP and verify that internet access is allowed.



When you receive a notification error Minecraft$annotatedconnectexception: Connection Refused on Minecraft, this means that Minecraft failed to connect to a server due to:

  • IP address issues
  • Outdated Java software
  • Blocked firewall permissions
  • Incompatible programs or apps installed on your PC

To resolve the issue, you can try doing a powercycle, or you can configure your internet settings. If your IP address isn’t static, check if your IP address and port are correct in Minecraft Settings.

If you’re using your own server, possible solutions include changing Firewall Permissions and portforwarding your network. If you’re using someone else’s server, allow Minecraft and Java apps under Firewall permissions.

If these solutions don’t work, contact your internet service provider.
