i developed a access control with MFA. the problem is that the mfa is regarding the correct mfa code as incorrect

I tried changing the authenticator and made some changes to the code hoping it could accept the correct Mfa

@app.route('/verifyMFA', methods=['POST'])
def verify_mfa():
    """Returns the page where you enter MFA Code"""
    return render_template('verifyMFA.html')


@app.route('/confirmLogin', methods=['POST'])
def confirm_login():
    """Called by web application to verify if MFA Code is correct"""
    mfacode = request.form['mfacode']
    totpauth = totp.TOTP(app.secret_key)
    if totpauth.verify(mfacode):
        write_log(f"User {session['name']} logged into the system.")
        flash('You have successfully logged in.', 'success')
        if session['role'] == 'admin':
            return redirect(url_for('user_mgt'), code=307)
        else:
            return redirect('/')
    else:
        flash('incorrect MFA Code entered. Try Again!', 'error')
        return redirect('/login')

THATS THE CODE
