trouble with beanstalk_console

Inside my beanstalk_console directory

After doing php -S localhost:7654 -t public

and going to localhost:7654 on browser

I get

Fatal error: Uncaught exception 'Pheanstalk_Exception_ServerException' with message 'Unhandled response: ' in /Users/myname/Code/beanstalk_console/lib/Pheanstalk/YamlResponseParser.php on line 43

any idea why?

Thx

The localhost:7654 was showing me the console server add screen before, however while I was trying different options to fill in Host in the add server screen , i messed up something causing this.
