Connection error timeout

Please help. I created a gradio app 4months ago based on a machine learning model, It was working quite fine but then I tried the app today at first it showed that it had stopped due to inactivity. I restarted it but it didn’t work, it only loads till eternity and come up with “connection errored out”. The space link is Here

When I get that in a space, a page refresh sometimes clears it up. Otherwise, I restart the space.
