Prefect Community

Hi, I recently tried to update from Prefect 3.0.3 to 3.1.3 and I ran into the issue that all deployments disappeared from the UI. When I deploy the deployments, it succeeds but they are not visible in the UI. Another similar but almost opposite problem is that when I add a block in the new version, then it shows up in the UI but `prefect blocks ls` shows an empty list.

I suspect it has something to do with 127.0.0.1 vs 0.0.0.0 as the host but I have no clue what is going on. Could someone help me out?

What exactly is the difference between the api.url setting and the server.api.host ?

I filed this bug that might be related: <https://github.com/PrefectHQ/prefect/issues/16019>
