Recorded Could Not Start, please check the log

I restarted the System: Hass.io → System → Host System → Reboot

Recorder was running before, but now I get:

The Recorder could not start, please check the log

And its listed as ‘1 day ago’ !!!

Found these in the System log:

19-04-10 07:13:01 WARNING (MainThread) [hassio.updater] Can't fetch versions from https://s3.amazonaws.com/hassio-version/stable.json: 
19-04-10 07:13:16 WARNING (MainThread) [hassio.tasks] Watchdog found a problem with Home Assistant Docker!

The times are correct, but the dates are Yesterday!

This is in the about log:

Error during connection setup: (MySQLdb._exceptions.OperationalError) (2005, "Unknown MySQL server host 'core-mariadb' (-2)") (Background on this error at: http://sqlalche.me/e/e3q8) (retrying in 3 seconds)
April 10, 2019, 3:14 PM components/recorder/__init__.py (ERROR) - message first occured at April 10, 2019, 3:13 PM and shows up 10 times

Again the date and times are wrong, even though it shows the correct time zone for me when I click on it.

And finally, of course, NONE of the Add-ons auto-started.

Why is nothing working?
Does this even work at all?

I see on the Hass.io System Information Hass.io Supervisor windows that I can “Join Beta Channel”
Would that be a step up from this Pre-Alpha version I’m apparently running now?

Home Assistant 0.91.3

Same network but different gateways don’t sit well with Hassio

Hi DaHai! Can you explain some more how you solved this problem. I have the same one
Thank you!!
