Same as: - https://bukkit.org/threads/error-starting-bukkit-server.206667/ - https://www.minecraftforum.net/foru...rt-and/2842587-server-not-working-no-idea-why - https://www.spigotmc.org/threads/server-not-starting.9354/ - https://bukkit.org/threads/server-not-starting.477592/ (not sure) Now I solved with creating a new user account on my computer. (This error worked on the older machine, but not now.) I recently purchased a Windows 10 Pro computer and when I wanted to run a minecraft server, I get this error: https://pastebin.com/XYecK6wz What I have done on page 3, but they didn't help. When I start the server, it will spam this error immediately after 3 seconds and stop it only after 15 seconds. I have never encountered such a mistake (as a developer) when creating a minecraft server. I'll tell you a couple about the machine and the server information: These are in my computer settings: - The first is that Windows is activated and working because it is a company. - I have recently changed the user tab and have only changed the profile image for the time being. These are on the server: - The server doesn't actually generate anything at all, only two files contain jar and the start bat file. - The start bat file is on the right path to run the server, as it was in the past. Java Settings: - Newest Java jre1.8.0_191 installed. - In fact, Java is only disabled when I turn on my computer and throws up an empty console. What should I do about it? Maybe change the user name in PC settings?
