This is what I found in renderd logs:

In my experience this means it's taking too long for renderd to do ad hoc rendering and you either need to pre-render most tiles or increase the resources renderd has to work with. You could test this by trying to reproduce the 404 error on tiles that you pre-render. If you can't reproduce it you could infer that the issue is the time it takes to render a new tile.

It's not that. I sometimes get 404s instantly and the instance has 4 vCPUs and 8 GiB memory. I tried on bigger machines and the same problem persists.
