Hi,
I am trying to connect to an LwM2M server using thingy91. I have Leshan demo-server hosted remotely on cloud it provides me IPv6 address to connect, as my network provider provides only IPv6.
I have setup all the security configurations of the device on the server side as shown in the documentation. I have setup same credentials on the device side using credential management AT command and saved it to NVM.
I am using ncs v2.2.0. I changed server address and port, enabled CONFIG_NET_IPV6 in the prj.conf file of lwm2m_clinet project in samples. built and flashed the application to my device.
I am not able to connect to the lwm2m server from my device.
Here are some of the logs:
