What is it about? what can i do?

EDIT: I got time to debug a little further and i found out that the response body looks like this, so a 404 on a "/talkgadget/_/extension-start" page

  <p><b>404.</b> <ins>That’s an error.</ins>
  <p>The requested URL <code>/talkgadget/_/extension-start</code> was not found on this server.  <ins>That’s all we know.</ins>

Edit2: Debugging further more i realized that "npm install hangupsjs" installs an old version that links to talk instead of hangouts url. Solved by compiling the new source code and copying in the node_modules folder

yakyak / hangupsjs
