licence expired on NAS

[Peter StreamMagic]

MinimServer stopped working on my NAS mentioning my licence was expired on 23-8-2022.
After a restart everything works fine again but I wonder why this has happened.
I did do a restart after renewing my licence on 10-08-2022 according the instructions "Thank you for purchasing a license subscription for MinimServer 2 updates and MinimStreamer. You need to restart MinimServer to activate the extended expiry date of 23 August 2023." The log gave no other information than MinimServer was still running while the icon was red.
