Error in login Upstox account

I am trying to create a application where multiple upstox accounts can be logged in at same time.
{ Something went wrong. Please try again after some time. [1017127] } this is the error i am receiving after entering the mobile number in the upstox pop up login window.
Is it not allowed to login upstox account with mobile number different than the one used to create the app for api’s?
If it is, please help regarding this.

Certainly, the mobile number used must be associated with the account used to create the app.

If you need to log in to multiple accounts through a single app, then you have an uplink business use case. Please complete the contact form at this link: Free Business Trading API With Unlimited Modifications @Upstox. A representative will then contact you for assistance.
