When I run this command sudo java -Xmx2G -jar forge-1.12.2-14.23.5.2838-universal.jar nogui This is what gets output in my console. A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap') at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more I'm doing this with a freshly installed forge server. I used the installer, not the universal. I've already tried uninstalling every version of Java I had installed and I've tried specifically with Java 8 and got the same issue. The issue came up kind of out of nowhere. I was updating the mod files and everything since the modpack we were running on the server updated, and after replacing the mods, scripts, config, etc. folders in my server directory I suddenly started getting errors when I tried to launch the server again. Edit: Just thought it might be worth mentioning that when I try to launch a vanilla minecraft server out of the same directory and on the same game version, it works completely fine. Edit Again: Attached the console logs that show me installing the forge server then trying to run it and it not fucking working logs.txt

Yeah it turns out we were just dying too much and the server needing to load new chunks constantly couldn't handle it. If your hardware isn't the best and you find your server crashing consistently it's probably cause your max players is too high.

Not sure what's causing the crash, here's the crash report. Any help would be greatly appreciated. server_crash_log.txt

Here's my matching logs. logs.zip

Where do I find my client logs? Edit: Nevermind I found them. Attached to original post

I'm trying to set up a forge server for a newer modpack called RLCraft, and at this point the server seems to be running properly. People can join as you'd expect them to until I actually add the mods to the mod file. I copied the mods directly from the modpack and pasted them in the mods folder. When I try to join, it tells me I have fatally missing registry entries. Any help would be greatly appreciated. All logs from the server are attached. logs.zip more logs.zip
