Thanks in advance. looking forward for response.

Could you please someone give solution for this issue. due this 2 reflection got failed continuously.

Thanks,

Port 45678 is what Dremio uses for internode communication, specifically to the executors. Seems like there is an issue connecting to them. What is your deployment like? Maybe try a full service restart of all nodes?
