I try to connect with blynk server, the fact is that the first time I did it worked but then I tried to connect through the 3g phone network and it stopped working.
then try again to open the application of my android and through the router as the first time and it did not work anymore.
I deleted the account, created it again, changed the pass, reinstalled the app, etc. but it still does not work.
my android app not login.
