Regarding the port problem of nightmare simulator, I need to explain that the port used by nightmare simulator is fixed and can be set by myself. The default port number is 6200 1, but in actual use, you can change the port number through the setup interface of nightmare simulator.
So as long as the port of Nocturnal Simulator is correctly configured, Zhu Xian can run normally on Nocturnal Simulator. If you encounter some problems, I suggest you check whether the port configuration is correct and make sure that no other program on your computer occupies the same port. If you still can't solve the problem, you can try to contact the official customer service of Night God Simulator for help.
