Server 2019 Multifiles c8 error

Hello my friends. I want to open 6x game server in Windows Server 2019. I managed to turn it on but I get a c8 error while connecting. I can open 3xGS in files given by a friend, but when I try to do 4x it gives a c8 error. Can anyone help?

please help

Port,IP,Cert config problem. I guess you should ask Syloxx to set it properly, tho his services arent free... Linking multiple modules to each other and make everything working is comolex and the solution is 'lies in the deep'. I think none could give a constructive idea what to do, only who made that multiplicated module config...
