Pool pump stopped working

[CapnPicard]

Long story short, I use Tuya local for 3 Tuya devices (Pool pump, pool heater and pool lights, same brand).

They all worked flawlessly for 1 year, then yesterday, the pool pump entity went offline in HA.

I checked the logs and I see this.

I tried to restart my pump, no effect. I deleted the entity and tried to add it again. Tuya local finds it, it detects its IP again, local key and everything, but when I tried to add it, I get this

I have no idea why.

Note that the pump still works with the tuya app. The other devices still works too in home assistant (heater and lights).

So only this device stopped working with tuya local for unknown reason.

Any idea?

thank you

I just want to add that I used a script to listen for tuya broadcast and my pump is broadcasting. Also the port 6667 on the device is open.
