Connection error in Android app

Hi I generated an apk (tutor android build debug) from a Koa instance on my macOS BigSur machine. I have connection error (“Connection error. Please check your internet connection”) when I register/sign-in through an Android emulator (apkonline.net). I tried other apk (not tutor) and it is OK. Appreciate inputs on how to go about this. Thanks.

Hi Nadheem, apologies for the very late reply. Been under the radar for some time. Thank you very much for your inputs! Will work on this. Cheers, Newt.
