WhatcouldIknow

I decided to make a server for me and a friend, sadly I had to encounter multiple issues which I fixed by now, one remains: The Server won't start up. I honestly got no clue, renewed Java versions, tried the latest and the one that was active in 1.16- times. Heres the latest log: [30Aug2024 00:30:50.124] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher running: args [--gameDir, ., --launchTarget, fmlserver, --fml.forgeVersion, 36.1.0, --fml.mcpVersion, 20210115.111550, --fml.mcVersion, 1.16.5, --fml.forgeGroup, net.minecraftforge, nogui] [30Aug2024 00:30:50.126] [main/INFO] [cpw.mods.modlauncher.Launcher/MODLAUNCHER]: ModLauncher 8.0.9+86+master.3cf110c starting: java version 1.8.0_391 by Oracle Corporation [30Aug2024 00:30:50.512] [main/INFO] [net.minecraftforge.fml.loading.FixSSL/CORE]: Added Lets Encrypt root certificates as additional trust [30Aug2024 00:30:50.542] [main/INFO] [mixin/]: SpongePowered MIXIN Subsystem Version=0.8.2 Source=file:/C:/Users/Leand/OneDrive/Desktop/Server/libraries/org/spongepowered/mixin/0.8.2/mixin-0.8.2.jar Service=ModLauncher Env=SERVER [30Aug2024 00:30:51.407] [main/INFO] [cpw.mods.modlauncher.LaunchServiceHandler/MODLAUNCHER]: Launching target 'fmlserver' with arguments [--gameDir, ., nogui] [30Aug2024 00:30:51.479] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: java.lang.NoSuchMethodError: sun.security.util.ManifestEntryVerifier.<init>(Ljava/util/jar/Manifest;)V [30Aug2024 00:30:51.479] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.SecureJarHandler.createCodeSource(SecureJarHandler.java:66) [30Aug2024 00:30:51.480] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.TransformingClassLoader$DelegatedClassLoader.findClass(TransformingClassLoader.java:275) [30Aug2024 00:30:51.480] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.TransformingClassLoader.loadClass(TransformingClassLoader.java:136) [30Aug2024 00:30:51.481] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.TransformingClassLoader.loadClass(TransformingClassLoader.java:98) [30Aug2024 00:30:51.482] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.ClassLoader.loadClass(Unknown Source) [30Aug2024 00:30:51.484] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.Class.forName0(Native Method) [30Aug2024 00:30:51.485] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at java.lang.Class.forName(Unknown Source) [30Aug2024 00:30:51.486] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraftforge.fml.loading.FMLServerLaunchProvider.lambda$launchService$0(FMLServerLaunchProvider.java:51) [30Aug2024 00:30:51.487] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.LaunchServiceHandlerDecorator.launch(LaunchServiceHandlerDecorator.java:37) [30Aug2024 00:30:51.487] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:54) [30Aug2024 00:30:51.488] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:72) [30Aug2024 00:30:51.490] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.Launcher.run(Launcher.java:82) [30Aug2024 00:30:51.491] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at cpw.mods.modlauncher.Launcher.main(Launcher.java:66) [30Aug2024 00:30:51.492] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraftforge.server.ServerMain$Runner.runLauncher(ServerMain.java:63) [30Aug2024 00:30:51.497] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraftforge.server.ServerMain$Runner.access$100(ServerMain.java:60) [30Aug2024 00:30:51.498] [main/INFO] [STDERR/]: [java.lang.ThreadGroup:uncaughtException:-1]: at net.minecraftforge.server.ServerMain.main(ServerMain.java:57) I regret to inform you that you shouldn't expect fast replies, Would love if you could help me out on this one.
