Fixing Network Lag issues
If you believe your problems are coming from your internet connection, you can try performing a speed test. The Ookla speed test website can show you at what speed your internet is running. It checks both download and upload speed.
In case your internet is the issue, you may want to check if your server is running on a WiFi flash drive, or is hardwired with a cable.
Internet cables have persistent connections and will not interrupt your internet. Also, they will take a large portion of your internet when sharing, and give you a boost, instead of spreading the internet evenly. After all Minecraft servers require a persistent and strong internet connection to run smoothly.
- If you are hardwired, try to restart your router, and see your internet once the connection has been restored.
- If the issue persists, you can contact your ISP (internet service provider), and ask them to check the issue with your internet. It could be a router issue, or your connection is slow and requires an upgrade.
Fixing Server Lag issues
For those who have been playing Minecraft on the same machine where they host their Minecraft server, you can check how many resources your computer is using.
- If you see the resource usage is too high, close down all applications, and leave the important ones.
For the sake of the troubleshooting, you can leave your Java, Minecraft Launcher and server working. The rest of the applications can be stopped.
- Another way to fix the Can’t Keep up error is to allocate more RAM to your Minecraft server. This way you will see if the resources were not enough, and can start the server without issues.
- If none of these helped, you can try to add SSD to your computer and put all of your Minecraft server files there. In this case, your server should start without issues.
If any of those steps did not help, perhaps your CPU is having issues or is malfunctioning.
- Remove the CPU that has been making issues, and change with another one. If the new CPU lets your Minecraft server resume working, you can just use it.
