Depending on your version of Minecraft, you may get an error message that looks like this:

  • connection timeout
  •$AnnotnotatedConnectException: The connection has expired.
  • Channel$AnnotatedConnectReception: connection refused: no more information available.

The error text does not give too much information, but it does mean that there is a problem with the connection. The text may vary slightly, but the basic problem, which is the inability to connect to the server, is the same. This error can occur for various reasons, such as the Windows Defender firewall or third-party antivirus software preventing Minecraft from connecting to the Internet.

What causes wtbblue.comnel error in Minecraft

After receiving many reports from several users, we investigated the problem and came up with several solutions that solved the problem for most users. We also looked at the causes that cause the error and listed them below. These include:

  • IP problem: In some cases, the problem is caused by the wrong IP address or a port specified when trying to connect to the server. The correct IP address and port are used to send your connection to the server, and the connection is established as soon as the server approves it. Unless you use a static IP address, which is rare, the IP address assigned to you by your ISP will change from time to time, and multiple users may be assigned to the same IP address. Therefore, the IP address must be changed from time to time.
  • Firewall: It is also possible that the Windows firewall you are using is blocking your connection to the server. The Java files and the game directory must be added to the Windows firewall exception list in order for the game to properly connect to the server.
  • Outdated Java: Minecraft requires that the Java software be updated to the latest version in order for the game to work properly. If Java is outdated on your device and the launcher has been updated to the latest version, this may cause conflicts with some elements of the game and prevent you from properly connecting to the server.
  • Incompatible Software: There is a list of software that is not compatible with Minecraft and will cause problems when installed on the computer you are trying to connect to the server. Minecraft has an official list of software that is not compatible with the game and will cause conflicts.
