Trying to make my first modpack but having issues

[DarkkeSpace]

Ive been trying to set up my first modpack server to use during streams and have spent several hours on it, however i cant figure out why it only launches in vanilla and not forge. Any help would be greatly appreciated as i cant figure out where im going wrong
