Request Error on :api/v1/channel/me

Hello,

We have configured the Mobile native app for android. However we are getting this error while signing in to one of our accounts.

"Request Error on :api/v2/Oauth/token"

Getting the same error on Emulator as well as Physical device. Also the website is hosted on a separate server.

Here is the error logs from Website server
