TheThingsNetwork - Entities stop being updated after a couple of days

Hi all!

Newcomer to Home Assistant here!

I built a small temperature and humidity sensor using an MKRWAN 1310, linked to my HA via LoraWan and The Things Stack. All works fine for a few hours or a couple of days, then the values are no longer updated in HA, while they appear in the App on TTN.

If I restart the TTN integration, measures are read again. Same if I reboot HA.

I checked the logbook, no error or issues, same for the logs: nothing related to TTN.

What can I check?
