Minecraft | Error: Invalid or corrupt jarfile server.jar

You will experience this issue if you try to manually upload a server.jar on your server files but it doesn't go well. It can be that the server.jar is corrupted in the first place or the server.jar failed uploading in the middle of the process

Go to https://help.skynode.pro/en/ and click on your server

Go to Change Version in top menu.



You can install a new server jar. We recommend to use PaperSpigot as it is more optimized than Spigot and Bukkit (also, bukkit will be disabled in the future)



Click YES



Once it is done, go to your Server Console and start your server.

All done! Your server should now be working properly!
