Error messages trying to OTA update devices using Z2M on a HA Yellow

Hi everyone.
Whenever I try to update a device using the OTA function, I get the following error messages:

 2024-10-31 14:42:03zh:ember:uart:ash: Received ERROR from adapter, with code=ERROR_EXCEEDED_MAXIMUM_ACK_TIMEOUT_COUNT.
error 2024-10-31 14:42:03zh:ember:uart:ash: ASH disconnected | Adapter status: ASH_NCP_FATAL_ERROR
error 2024-10-31 14:42:03zh:ember:uart:ash: Error while parsing received frame, status=ASH_NCP_FATAL_ERROR.
error 2024-10-31 14:42:03zh:ember: Adapter fatal error: HOST_FATAL_ERROR
error 2024-10-31 14:42:03z2m: Adapter disconnected, stopping

And I have no idea what any of it means. Can anyone help me translate this and maybe even help with a solution?
The hardware is a Yellow and the adapter is set to Ember.
