GWT 2.6.1 w/Eclipse 4.3 plugins under Windows 8.1: failed to open the sample webapp in Chrome (it's ok w/IE)

Pls help me w/GWT for 1st time use. GWT 2.6.1 was installed per http://www.gwtproject.org/gettingstarted.html

I followed the instruction on http://www.gwtproject.org/usingeclipse.html

The sample web app opens a page in IE v11 but not in Chrome 37.0.2062.120. Why?

It momentarily shows the title, Web Application Starter Project

and then this error msg: URL is http://127.0.0.1:8888/FirstGwtWebApp.html?gwt.codesvr=127.0.0.1:9997

Plugin failed to connect to Development Mode server at 127.0.0.1:9997
