Expected Behavior

Can reach the site when use local IP.

Actual Behavior

Cannot reach the site when use local IP.

For Bugs; How can we reproduce the behavior?

1. The local IP is 192.168.0.101 (example).
2. Set the useLocalIp option: webpack-dev-server --mode development --hot --open --useLocalIp
3. Open 192.168.0.101:8080 in browser
4. Got error:
   This site can’t be reached 192.168.0.101 refused to connect.
5. If I open 127.0.0.1:8080 or localhost:8080, it works fine.

Adding --host 0.0.0.0 fixed this for me.

192.168.0.101 is not local ip, use 0.0.0.0 as above if you want to attach dev server to all ip or use directly 192.168.0.101

Adding --host 0.0.0.0 could not fix this for me.

Works with webpack-dev-server --mode development --host 0.0.0.0 --hot --open --useLocalIp
