503 Service Temporarily Unavailable in the landing page

Hi Metabase support,

we are experiencing a bug. The landing page often shows 503. It happens intermittently. We have started getting this bug since 15th June 2023.

We tried to load the page in Safari and in Chrome but we got the same respond.

Here is the screenshot

Our Metabase is on version v0.46.1

Do you know why that is the case?

Below is the diagnostic info.
