● An issue associated with your IP

According to the gathered information, this issue can appear due to an error in your IP address. It can trigger due to an error in the connected port when connecting to the server too. Basically, your IP address and the port number are used to establish a connection with the gaming server. If you are not using a static IP address, your IP address will change pretty frequently by your ISP. So, the chances are that the same IP address can be allocated to different users at the same time. Therefore, it is always required to change the IP address.

● Due to the existence of your firewall

Under certain cases, the connection between your computer and the gaming server can be blocked by your firewall. This is particularly true if you have not whitelisted the game’s server connection with the firewall. In this case, you should add the game directory and the Java files to the whitelist. As a result, the connection to the game will be permitted by the firewall.

● You are running an outdated Java version

You may already know that Minecraft wants the latest Java version on your computer to function smoothly. If you are running an outdated Java, and your launcher is updated to the newest, that triggers a conflict. As a result, some components of the game will not be connected to the server properly.

● Your software is not compatible

There are several software tools that don’t work in harmony with Minecraft. If you try to run one of those applications with Minecraft, conflicts can emerge. In fact, their official website shares a list of software applications that are incompatible with the Minecraft game. So, go through the list and check if your computer has at least one of those applications installed. If it does, you should uninstall it and retry.
