After few days of work I can no longer connect to my puck

Hello
I had my puck running for 3 days without an issue as a power meter.
But then it stopped reading the data as a power meter and I can no longer connect to it.
It still sends current battery and temp statuses.
When I try to connect to it I get this:

Disconnected from Web Bluetooth, Puck.js 1c30
Unable to retrieve board information. Connection Error?
Connected to Web Bluetooth, Puck.js 1c30 (No response from board)
