Notice
On Unix systems, localhost and 127.0.0.1 have different connection behaviors. When using localhost, OBClient attempts to use a Unix socket connection; when using 127.0.0.1, OBClient uses a TCP/IP connection. If your server listens only on TCP/IP ports, use 127.0.0.1 or the actual IP address.
