Login error on qa-refapp

I am unable to login to qa-refapp from the android app. The website is working fine but from the android app I am getting invalid login id or password. Credentials used : ID - admin Pass - Admin123 URL - http://qa-refapp.openmrs.org/openmrs

The REST API on the server is working fine because the app is able to fetch the locations properly. I have tried the to compile the app from android studio and also tried the app published on Play store on three different devices and with two different networks. Ping @dkayiwa @avijitghosh82 @raff

After failing to login from the android app, you could try login using the browser with the same user name and password to see what happens.

As I mentioned there is no problem in the website.

Using https instead of http solved the problem.
