Access Error : Device reports a unavailable object.

Hi Mikko,

Initially, I have connect meter using high-level security. Then set the secret from Association 0.0.40.0.5.255. Now I am trying to connect a meter with updated secret but not able to connect.

Can you please check the following logs and provide an update.

Let me know if you require more information about the same.
