Hey @zain . This is pretty strange, lets see if we can narrow down what is causing this.
1.) What modem model are you using again?
2.) What base image does your docker container come FROM
3.) does your base image have the INITSYSTEM=on environment flag set which enables systemd?
I just preloaded my 2.0.0+rev2 RPI3 with a basic node.js webserver example. The device has a Huawei ME909-u LTE modem for the connection. It all seemed to work right out the gate, so I haven’t been able to reproduce it. I am wondering if its perhaps got to do with something in the base image as we have been trying to debug in this issue: Cellular Modem connectivity issues on boot
