Alishahareem I see you're using Hostinger, can you double check Litespeed isn't active as it isn't compatible with Ezoic and would drive the cache hit rate down.
Aside from that, you've set your maximum cache age at 30 minutes, our default cache age is 30 days. I'll update the maximum cache age for you and I'm certain this'll improve the cache hit rate, and site speed, over the next week or so 😀
