Dubbo registration service IP parsing is abnormal

The service will be stuck for a while, and then abnormal output:

[DUBBO] Could not get local host ip address, will use 127.0.0.1 instead., dubbo version: 2.6.2, current host: 127.0.0.1

Solution:
modify the hosts file bound to this machine.
vim / etc / hosts configuration:
192.163.191.1 (ipaddress) localhost (hostname)
