Minecraft Server Error: Failed To Bind To Port

Last modified on Nov 29, 2022 in server errors

mc head By ApexHosting


When opening a Minecraft Server, the last thing anyone wants to encounter a console error that is preventing the server from properly running. Unfortunately, this can happen quite a bit with quite a bit of different errors. One of the less common errors that can run into is a failed to bind port. The failed to bind to Port Minecraft server error occurs when a server attempts to use a service port (i.e 25565) that is already in use by another server. Since the majority of Minecraft hosting is Shared Hosting with shared IPs, the only way to make each server accessible is by giving it a unique port.

The Problem

Failed to bind port

The exception was: java.net.BindException: Address already in use
Perhaps a server is already running on that port? 

Above are the messages you will see if you run into this error. The server will not be able to fully start, and no one will be able to connect.

How to fix the failed to bind port error

If you do not have a server with Apex Hosting, you will need to set the server to use a port that is open and not used by any other service.

However, if you are using a shared host, you will need to contact the host support team and state your server is encountering a "Failed to Bind" error and they will resolve it.

To Conclude

Since multiple Minecraft servers can be hosted using the same IP, they need to be assigned a unique service port to distinguish them between the other servers being hosted. As such, minecraft servers that utilize Shared Hosting are typically assigned a unique service port above the default server port (25565) and increase incrementally by one for each server (25566, 25567, etc). If you are experiencing this issue while using a server host, please make sure to contact the support team so they can get it resolved as soon as possible.
