Whenever i try to acess my website on my phone it says "safari couldnt establish a secure connection to the server" and i dont understand why bc hours ago it was working fine.

To give some context im using hostingers business plan hosting and i just applied astra theme today and started editing my website and this just happened at 5am i woke up and tried to checkout my website and to my surprise this is happening.

Can someone explain whats happening?

And if its a problem occuring bc of hostinger can anyone suggest any other alternatives for a small saas business like webflow or framer? Bc i genuinely dont wanna deal w my website crashing or whatever is happening when i literally just bought my hosting plan not even a month ago.
