Connection regularly “dies” silently

[mtjoernelund]

I am using Node-red-contrib-ikea-home-smart node which is based off node-tradfri-client. When I set it up it works as it is supposed to, but after it have been running for a period of time (hours), the tradfri gateway stops accepting commands. As far as I can see the gateway does receive the commands, but it just seems that it does not honor the commands. I’ve set logging to trace, but still does not get any useful errors to go by. All I get is feedback on commands being send where result is false rather than true as expected.

Sorry I know this is not much to go by, but was curious if there was anybody who could propose where I could start looking for errors? If I need to post additional information let me know.

If this is somewhat reproducible, maybe you could capture the traffic on port 5684 using Wireshark or something similar and send me the dump file and the key that is on the bottom of your gateway.

Please test with v2.1.4. Apparently the gateway has started expiring the identities after a while, so the library needs to re-authenticate when it detects that. For this to work, you need to always authenticate, then connect with the new identity and PSK.
