How are you @goviral? Can you tell us when was the last time your website stops working? and what was the last work you did on your site? so we will know what the problem is?
Your website is working fine from my end, but take time to load. I also notice you’re using WordPress can you use a plugin and purge your Site? here you can find such plugins https://wordpress.org/plugins/search/purge/
