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.
