So I am having issues with my FTB server it is hosted by an AMP panel but I don't think its related to why the server doesn't work.

Below is the error I get.
Code: 
A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

My Java version is:
Code: 
root@server3:~# java -version
openjdk version "11.0.6" 2020-01-14
OpenJDK Runtime Environment (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1)
OpenJDK 64-Bit Server VM (build 11.0.6+10-post-Ubuntu-1ubuntu118.04.1, mixed mode)
root@server3:~#

From what I can tell on AMP's Side here are the logs of the startup.
