When I wrote the code and and ran the Flask app and pay with they Razorpay payment gateway, they show me an error:

” Uh! oh!
Something went wrong
We appreciate your patience.While we fix this, continue browsing on 127.0.0.1“

So, how to solve this error?

While when I pay with Razorpay account link, then payment is successfully done, but using the API key and secret key in Python Flask app, they then show me this error, showed how to resolve it.

I was trying the test and live mode, but both showed me errors.
