Hi MCDes,
I just update the code to be compliant with nRF SDK 2.0.
Btw, keep in mind that the evaluation version of Iowa is limited to 2 minutes sessions (so maybe you won't be able to check :( )
One more point, if you are using UDP, this kind of behavior is not unusual (depends on NAT rules expiration timeout)
To isolate your issue:
- Test with TCP instead of UDP (if apply)
- Test on a different server (https://iowa-server.ioterop.com/ could fit your needs 😉 )
Hope this helps!
BR,
OlivierG

PS: On cellular IOT devices, we usually set the lifetime value to ...86400 (1 day)

Sadly, it doesn't compile.

You may want to check out if it is server or client related using IOWA:
