Can't able to make purchase through upi payment method in mac app store

Is UPI listed as a valid payment method for your country?

You can find the acceptable payment methods for your country here;

Payment methods that you can use with your Apple Account - Apple Support

M1 Mac mini, macOS 15.3.1;  Watch, series 10 GPS-only, watchOS 11.3.1; iPhone 16, iOS 18.3.1; TV 4th Gen, tvOS 18.3; HomePods, audioOS 18.3 and Airport Express w/ Airplay 2

Yes UPI is listed as valid payment method and I tried adding 2 different UPIs too thinking maybe one had some problem but none of the UPI are working. It says "Cannot Connect" every time I try to make payment.

That world wide support is useless. People attending the call are not technical people. They will put the fault on you or your bank, saying go to the bank for further support. I have talked to them several times, trust me.

Have you spoken to UPI to see what they see happening on their side of the trans action?

Have you spoken to Apple Support?

Exact same thing is happening with me as well. Something from Apple's side is broken. It is so frustrating.

Have you spoken to UPI as I suggested yesterday?
