Odata and status code 503. macOS 13.4 22F66. FileMaker Server 21.1.5.500

We had a server that just stopped working with odata.
Started with timeouts. We turned odata off and on and then got 503 responses.
Turned it off and on again and still got 503 responses.

Rebooted. odata was off. Turned it on and it now works again.

From. the command line

  1. Using some FileMaker tool can you tell if a FileMaker Server service is offline?
  2. Can that service be restarted?
  3. Can a server be cleanly restarted?

Cheers and thanks!
