Jetson nx can not restart automatically:

hello,
i works on jetson xavier NX with jetpack 5.0.1.
and i found a problem after my NX runs after 20 days 7*24 hours with deepstream6.1 at outdoor:
5G router was stopped somewhile, and NX can not restart automatically even let somebody power on again. and of course i lost network, can not control it by SSH again.
my adapter is original 19v 2.65A.
could you give some advice for the problem?

thank you very much!

and my power mode setup: 20W 6 cores.

thank you

That may need to clarify why 5G network lost.
May need to have some log to do further analysis.
