Chateau 5G ax - destroying lte1, device stat down

Hi I hope someone can help me understand what this means.

I get this message - destroying lte1, device stat down - in my logs and it appears as my LTE goes down on my router. Im not sure what’s casing it out how I can fix it. Has anyone seen this before?

The SMS sent via LTE is after my router was rebooted.

The LTE will come back on but I also have an additional interface that will show up when the LTE disappears and remains in the interface list once the router has been rebooted.

Any help would be appreciated
Thanks
