Problem with WemoMini random disconnect to the ESPHome in HA

I have Wemo Mini Board for 2 garage doors connected to HA using ESPHome Intregration. Working fine for a few weeks but now unable to communicate to the board. I even reset by powering off and on, still not able to connect using the ESPHome on HA.
But when I take the Wemo board and moved to my test bench it connect to the ESPHome just fine. Then when I put back to the original location it works for a few days then it quits connecting to the HA even with hard reset. Does anyone know why it happen and how to fix this strange problem?
