Unknowingly removed security tag 24 in AT%CMNG

[tsotnek]

Hello,

Long story short, I was trying to make the JWT authentication work for the NRF cloud and I was writing and removing the certificate and keys to the modem. I removed the certificate with security tag 24. Could that have caused the problems with the modem? Now it seems I am no longer able to connect to LTE network. When I run the command AT%CMNG=1 this is the returned message:

OK

P.S. I can't even run the Asset Tracker V2 sample on my nRF9160-DK when I press Start button in Cellular monitor this is what gets printed in the log.

Error when creating trace: error: ERR_SERIALPORT_OPEN message: Win32 open serialport error: Access is denied. plugin path: C:\Users\tsotnek\.nrfconnect-apps\node_modules\pc-nrfconnect-cellularmonitor\node_modules\@nordicsemiconductor\nrf-monitor-lib-js\Release\win32-x64\nrfml-insight-source.nrfml

Ok so it appears that the modem was in Reset_Loop and also my sim was blocked because of too many requests. But regarding this certificate with tag 24 I am still not sure if it something important or can be ignored.

Glad to hear that you found the source of the issue.

sec tag 24 is likely something you've used in one of the previous samples that you've tested, no problem that you erased it.

 

Kind regards,
