I Face Instagram Access Blocked by “Check Security Code” Error After Duo Mobile Login

I set up two-factor authentication for my Instagram account using the Duo Mobile app, but now, even when I enter the correct codes, I keep getting the error message: “Please check your security code and try again.”

No matter how many times I try, the same warning appears, and I can’t log in to my account. This issue has completely locked me out of my Instagram profile, and I’m really struggling because of it.

Please help me resolve this issue so I can regain access to my account. I’m genuinely frustrated and feel stuck since I can’t get past this error.
