plugin failed to connect to hosted mode server at...

I created a simple project that uses gwt and gwt-maps.jar, which
worked few days ago, and now all of a sudden not working. I recreated
it multiple times but no luck. Every time i put address into my
browser I get 'plugin failed to connect blah blah'

After running it Chrome the dev mode window gives me these errors:
