It's working! Thank you!
Hi I made a server It worked 2-3 weeks but after it says : We appear to be missing one or more essential library files. You will need to add them to your server before FML and Forge will run successfully.java.lang.ClassNotFoundException: net.minecraft.launchwrapper.Launch at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(Unknown Source). I am using MyMcAdmin it was working but Its now dead. There is the log of my software.
