Everything is as I said, no one will be able to make the server visible on the Internet on the Linux system, well, now I'm at least sure of it, thank you for checking this, I'll have to switch to Windows to raise the online of this game, in the opposite case, using the server in this way leads to loss of online, or I will have to aggressively advertise my server and recruit people, but in any case, I think it's easier to switch to Windows server and not suffer, although I will be very glad to see who can solve this crazy puzzle
