  <p>Here is my manifest.json ( Note the private IP in (192.168..) in my update_url. ):</p>

     "key": "MIGfMA0GC...B",
     "name": "Test Plugin",
     "permissions": [ "http://*/", "https://*/" ],
     "plugins": [ {
        "path": "TestHost.dll",

  <p>For some reason clicking on "Update extensions now" doesnt work. So my plugin is not getting updated. In wireshark i see no HTTP request going out at all.
  I have few other extensions like adblock and gmail extensions etc, even those are not getting updated.</p>
  
  <p>Only thing that i did different was that i manually added "update_url" in my manifest.json after installation of my test plugin. Should that work? If yes, what could be the reason that i don't see any GET request in wireshark?</p>
