I Face Instagram Login Failure Even With Correct Duo Mobile Code

I set up two-factor authentication for my Instagram account through Duo Mobile on my old device. Even though I know and correctly enter all my account information — email, phone number, and password — Instagram won’t accept my Duo Mobile verification code.

I’ve tried logging in from both my new and old devices, but it still doesn’t work. I’m completely locked out of my account and can’t regain access despite having all the correct information. Please help me recover my account or fix this verification issue as soon as possible.
