MinimServer 2.1 on QNAP TS-228A available or not?

[simoncn]

According to the QNAP App Center web page, the MinimServer 2.1.2 package is available for a TS-228A running QTS 5.0.1.

I don't know why you are not seeing this version as available when you open App Center on the NAS. Are you running QTS 5.0.1 or an older version?

Can you download MinimServer 2.1.2 from the QNAP web page and do a manual install? It seems very strange that QNAP would require you to do this.
