hAP AC3 LTE6 fails to upgrade to 6.47.2

Howdy,

I have at home hAP AC2 and hAP AC3 LTE6. Former nicely “reports” (via webfig) the presence of new OS release, downloads change log and all as expected.

OTOH, the hAP AC3 does show the version only of new firmware, but kinda the webfig gets stuck, as changelog is NOT shown (only of the instaled 6.47.1), also the Download button either disappear or simply does nothing.

Any idea what may be wrong?

Reorded short vid about both:

hAP AC2 “the good”: https://www.youtube.com/watch?v=6M95gjy4IVc
hAP AC3 “the bad”: https://www.youtube.com/watch?v=VZpNcgOGFeQ

Both are on same LAN, same ISP/GW

Update via WinBox using NPK file.

Regards.

Meh, answer I was afraid of (am on linux). Ok, so installing wine…

Ok, wine64 works seemingly fine.

And from where to get the npk file for hAP AC3? The https://mikrotik.com/download page does not enlist it (not the board RBD53GR…)
