java.lang.NullPointerException: Cannot invoke "abr.o_()" because "☃" is null

The problem has been solved, the specific reason is unknown (I am sure that two servers are not opened at the same time), and the problem is solved after reboot is used to restart the machine

The server is already running, but I think there are still problems with it
