Hi,

At this point we were able to figure out the problem on the network provider side and got everything running again. Thank you for your help either way!

Best regards,

Florian

Hi Michal,

We are using the modem fw v2.0.2. and the zephyr v3.5.99-ncs1-2. Unfortunately providing modem traces is not possible at the moment.

I think all in all there seems to be a problem with the "mobile network backend" of the provider, as we don't see those problems with two other providers. After I found the TLS handshake timeout I thought it might have been a good idea to lower that value to speed up the process. Is that even possible ?

Hello Flo,

Which NCS and Modem FW versions are you using?

Are you able to provide the modem trace showing this issue?

Best regards,

Michal
