How to Fix Failed to Bind to Port on Minecraft Server
Are you running into the "Failed to Bind to Port" error when starting Minecraft server? This issue usually means the server port is already in use or another instance is still running in the background. Whether you're using a Bukkit server, a vanilla build, or running multiple servers, this issue is very common and thankfully, fixable.
If you see the following errors in the console or log, both have the same message meaning.
This error usually means your Minecraft server can't claim the port because it's:
Same port in use by another process
Still being held by a previous server instance
Misconfigured in the server properties file
It is very rare to experience this error using our services, but if you do, you will have to contact our support team to fix this error message and get your server properly back online as soon as possible. You can also check out our guide on how to contact Sparked Host Customer Support.

This message has nothing to do with your router or port-forwarding settings.
The most common reason is that another instance of the server is already running on the same port. If you can’t find the corresponding console, the server might have crashed**Contact us for assistance**.
This issue can also occur if you're not connected to a network. Ensure you're connected to your router and follow these steps:
Restart your computer.
Run the command ipconfig to renew your IP configuration.
Go to the Network and Sharing Center and choose the option to troubleshoot problems. Although the Windows troubleshooter isn't always reliable, it can help establish the connection.
Ensure your network drivers are correctly installed.
