If your PC is connected to a wifi or network hub the "127.0.0.1" in the error message could indicate the PC 's network cards had become temporarily disabled. Just a suggestion as could be caused by many things. Error -102 is the Chromium code for "connection refused" - its the computer equivalent of being invited to a party and finding when you arrive either the party was cancelled or the security at the door won't let you in - there's probably a better analogy but can't think of one at the moment.
