Expected behavior

I have successfully installed Xabber app on my android device. Then I was instructed to create Xabber account, then I chose to Sign Up, and chose to Sign Up using my Facebook account, after I filled my email address and Facebook password to get in I got problem "Error with login: d.a.a.e: HTTP 400 badRequest".

Actual behavior

The problem still occurs, even though I have tried to log in repeatedly. And I uninstalled this app and then reinstalled it. But the same problem still happens. I can not Sign Up using my Facebook account. And get the information "Error with login: d.a.a.e: HTTP 400 bad Request".

How to reproduce

Install the Xabber app on your android device, then open it and run this app. Then select "Create an account Xabber", then click Sign Up, and select Sign Up using a Facebook account, then fill in email and Facebook password, then click login. Then you will get the problem as I have explained, "Error with login: d.a.a.e: HTTP 400 bad Request.
