Disconnect server

[somebody123123123]

Hello everyone! Sorry for such silly questions. I have the Louisa Season 8 Update 31 build, I configured the servers and they launch, but I can't connect — the server immediately disconnects me. I tried different options, but I think the problem is that the main.exe file is version 1.5.7.0, while the version listed in the server is 1.04.09. I tried downloading different main.exe files, but they give errors saying some files are missing. Please help.
