Website can't be reached

[MrMango069]

Whenever I search for my store or try to view it, it says it can't be reached. I have updated all the DNS, but initially, Shopify suggested 60 minutes for the TTL. However, when I tried to input this when editing the TTL, my domain provider said that the value was too low, so I kept it at whatever number it had initially. Can someone help me, please?
