Why are you using the unversal ?

what do you mean ? after downloading the forge i got multiple choices. like install client or install server. when im installing the server i got in my file the vanilla minecraft server that is working all good, and the forge one. that doesnt seem to work at all. the forge called "forge-1.12.2-14.23.2.2611-universal".

hope you understood.

Post your log files, without those we cant tell you why its erroring.

You could be doing a million things wrong, you've given us no information to work off of.
