Nostale launcher NosCore Help

[Kubkos1]

Hello, I tried all launchers from old ones to new ones, nothing works. I don't know if my server is broken, but I have all completely good builded and running. Login,Master,World all working. But I can't join to it. The most far I have got is with Delirium Launcher, but it says incorrect Username and Password, but I have the basic account: "admin, test". So please can anybody help me, to find the right launcher? If necessary this is my discord: TheArgent#6863. Thank you so much for any answers.

Best Regards,
Jacob.

Is NosCore not only for testing serverside and helping for programming of a Server? You can only use NosOpen with a Play Client without programming
