Hi,
I have a nRF9160DK with a Sim Card from a local provider, that supports NB-IoT.
I modified the example program in \ncs\zephyr\samples\net\sockets\echo and wanted to set up a connection from the nRF9160 to my TCP Server. That didn't work and then I tried to connect it to the Google DNS server as a test. That didn't work either and I am out of ideas now on what could be the problem. This is the error message I get from the LTE Monitor:
