My issue

I can’t find what is wrong with this attempt

My code

T = int(input())
for i in range(T):
    N = int(input())
    S = input()

    vowels = "aeiou"
    hard_count = 0
    for letter in S:
        if letter not in vowels:
            hard_count += 1
        elif letter in vowels and hard_count <= 4:
            hard_count = 0
            
    if hard_count <= 4:
        print("YES")
    else:
        print("NO")
