I’ve found the problem… testing with browser you have to use this chrome plugin:

I’m testing login to server by rest api and it works on browser, now that i’m installed the Chrome extension. On my server i’m logging all rest api call and i’ve seen that every login generate two api call, why?

Running same app on mobile (ios & android) via Ionic DevApp fail login, api send http request without parameters

Some help?
Thanks
