Cellular Problems with MBX Mini 5G

Hello,

Have any of you had the experience with a Peplink MBX Mini 5G that sometimes a cellular modem does not connect properly and gets stuck at the “Connecting” status and the cogwheel turns endlessly? It almost seems as if the modem is not getting an IP address.
After restarting the device, the cellular modem works again without any problems.
I am attaching a picture of the status here.

Firmware: 8.4.0 build 5736
Modem support version: 1026

Does anyone know what a solution could be?
