Hi Mark, Its a good point and no I haven’t.

I shall do that test over the weekend. A Vanilla version of Linux may not have the same logging capabilities as Balena, so I am still interested if anything is picked up. It’s 12hr drop out has just occurred. At what stage should I be able to access the persistent logs please and where are they located?

I also tried manually resetting the 4G HAT whilst the Pi is running which made no difference, device is still offline

Whilst researching, I also came across this thread, does that have any similarities to my issue perhaps?

Many thanks.
