Error while executing queries on multiple nodes

Hi Team,

We have been using the dremio community version 23. We are getting the below error on executor when executing certain queries which uses multiple executors for execution:

“2023-04-26 18:32:46,595 [FABRIC-2] ERROR com.dremio.exec.rpc.BasicClient - Failed to establish connection
java.util.concurrent.ExecutionException: io.netty.channel.ConnectTimeoutException: connection timed out: *.internal.cloudapp.net/:45678”

The port 45678 is open and there are no firewalls blocking the same.

Could you please help us resolve the same.

Regards
Sumi
