What Causes the Connection Refused Error?
After receiving numerous reports from multiple users we investigated the issue and devised a set of solutions that solved the problem for most of the users. Also, we looked into the reasons due to which the error is triggered and listed them below. For that: Now that you have a basic understanding of the nature of the issue we will move on towards the solutions. It is recommended that you try these solutions in the specific order in which they are provided to ensure that no conflicts occur.
Power-Cycle your Network
Whenever the internet router is reset the IP address that is provided by the ISP is changed unless you are using a static IP address. Therefore, in this step, we will be reinitializing the internet settings and the DNS cache by completely power cycling the Internet Router. For that:
Reset your Network Configurations
Your Windows Network configurations can also be a culprit here, as it’s possible that your Network settings are configured incorrectly. For resetting network configurations, follow the steps below:-
Add Exception in Firewall
It is possible that the Windows Firewall that you are using might be blocking your connection to the server. Therefore, in this step, we will be adding an exception in the Firewall for some executables in the Minecraft folder that need internet access. For that:
Add the IP address and Port Before Connecting
If the IP address that you are using is not a static one, it will change every couple of days or whenever the Internet Connection is reset. Therefore, in this step, we are going to be checking the IP address and the correct port for the game and add it to the Minecraft Launcher. For that: Note: There are some applications that are generally incompatible with certain elements of Minecraft and cause issues with it. The list of applications is available here. If these are installed on the computer on which the server is running from or on your computer you will continue to face issues with the game.
Check for Port Filtering
We came across numerous instances where users were accidentally filtering ports. Even though the port forwarding was working alright, the filtering automatically nullifies it and you will not be able to connect to Minecraft servers. Here, what you can do is check your router’s and your local machine’s network configurations and make sure that port filtering isn’t turned on and if it is, the correct ports are being filtered.
Check ISP Network Access
If none of the above methods work, you should check your ISP’s network access. ISPs sometimes block network access to specific domains and don’t allow you to go through. Contact your ISP and verify that internet access isn’t indeed blocked. Furthermore, you can also change your internet connection to your smartphone’s 3G and see how that works out for you. If it does, it probably means that your ISP is blocking you and you need to change your network. If Minecraft is working with the Mobile Data it means that your ISP is blocking the connection. If that’s the case please contact your ISP to get your issue resolved.
