Your server is not even started, because of some errors during startup. You can’t connect to a crashed server ^^
About that errors: Some of your coremods are loaded before Sponge, which causes Sponge to crash. Try starting your server with SpongeBootstrap. That might help…
Also this mod:
SpawnOfPsyduck-1.10.2-2.3.3-storagefix copy.jar is not loading due to some file error, maybe try to rename it to something without a whitespace character.
