Comment 4 for bug 1881275

It seems like the error is related to MAAS starting up. I tried having a tab open for MAAS where MAAS had been already started a long time ago. I couldn't reproduce the error.

But after leaving the tab open on the machine listing and then restarting MAAS, I see the error happening within a minute after the listing is showing again.

I don't see anything obvious in the logs, but this looks odd:

  2020-06-01 10:40:41 stderr: [error] request to http://127.0.0.1:5240/MAAS/metadata/2012-03-01/ failed. sleeping 4.: HTTP Error 503: Service Unavailable

It keeps trying, but never succeeds.
