Strahlend Posted June 12, 2017 Author Share Posted June 12, 2017 Thanks for the reply I found the issue. The launch wrapper was broken causing the error. Here is a link to download the fixed one.https://libraries.minecraft.net/net/minecraft/launchwrapper/1.12/launchwrapper-1.12.jar This is the file pathFeed the Beast Server\libraries\net\minecraft\launchwrapper\1.12 Then replace the launch wrapper with the fixed one and it works.
