Hi! I’ve encountered an issue a handful of times where the modem does not reconnect properly until reset (re-activating the connection solves the issue) i.e nmcli con up xxx
On this post Never reconnected after SIM desactivate/activate I found that it may be that the mobile operator issues a disconnection and the modem does not reconnect by itself. I have a gut feeling that this may be the same issue as what I am experiencing.
This has happened two or three times now, rendering the device unreachable since we are 9 times out of 10 relying solely on cellular connectivity.
Any chance anybody else has experienced the same issue and has found a solution? 
Here’s my current configuration:
[connection]
id=Cellular
uuid=11a739cc-fae9-4be2-a62a-8e2af06c7283
type=gsm
[gsm]
apn=<redacted>
[serial]
baud=115200
[ipv4]
method=auto
route-metric=25
[ipv6]
addr-gen-mode=stable-privacy
method=auto
Below is also a log dump of what happened, and at roughly 14:20 the connection manually activated using our own UI invoking network manager to activate the connection. The connection was still active according to network manager before manually activating the connection again
