QNAP HS-210 Issues with Minimserver 2.2

[gnomus]

As of today (3 Feb 23) I have been having issues with Minimserver 2.2. All was working well - in particular the update from 2.1 to 2.2 seemed to go without issue.

Now, however, Minimserver will not work on my QNAP HS-210 at all.

The first thing I noticed was that there was no server in my control app. Then on Minimwatch the icon was red. I had a brief message flash up about my licence. I did not catch all of this, but my licence should be valid up until late May.

So it was off to the QNAP 'webpage'. Attempting to start Minimserver via this page led to the following message(s):

Minimserver is stopped: to restart, use Stop and Start in the App Centre

(I tried this, but ....)

Minimserver is stopped: to restart, use Stop and Start in the App Centre

followed by:

Minimserver start error: java.lang.StringindexOutOfBoundsException: String index out of range: 4
Minimserver set to disabled

I rebooted the QNAP. I updated the QNAP firmware. But this has not helped.

I should add that I have made no recent changes to the library or my settings, so I am somewhat at a loss.

Any suggestions?
