Hi,
I'm using the asset tracker example code with the LWM2M overlay to connect to the Coiote server.
This seems to work fine, and messages do get through. But when booting the device I always get several errors as shown below. Is this normal behavior for a first time connection process?

So the specific error that I'm talking about are:

Appart from those error during the first connection I also get some errors during use after that, when it tries to connect again. Is this also normal or something that I should look into?
