I installed the newest 1.12.2 version of forge and made a new server. Then I put all my mods from my mods folder into the mods folder of the server, but it still didnt work. Wdym with "some of your mods are missing"/ "are the wrong version". I mean, it all works fine in Singleplayer, but the server won´t work for some reason. And also, since I directly copied all mods from one folder to the other, there should be no problems, as I thought...
I´ll link the new crash report.
