Deployed website does not load

I have deployed a webpage via render.

Though while it worked just fine, few hours later I can’t visit my webpage.
It’s stuck in the loading part.
The loading went too long that the connection timed out.
Also, I can’t access to the dashboard of that webpage.
I wanted to check what the problem was, though couldn’t access the dashboard and it kept on loading and then the connection timed out, just like my webpage.

Also, it’s not a free plan instead paid, therefore I believe that it has nothing to do with my memory.

What would be the problem?
And also, what is the point of using paid plan of render when I can’t even access to my webpage or the dashboard?

Please help me out.
Thank you.
