Hello Pedro, Thanks for reply. We are running standalone Flink on rhel 9 VMs. I was thinking maybe there is another setting I need to add. It is not using any port I already set. This can be a dynamically created port for Pekko maybe. I need static values for the ports so that I request that ports to be opened.

From the shared logs, I see the connection is being made by a high port rather than the ones you're sharing on the logs. What are you using on the underlying nodes to run Flink? Do you know why there is this port discrepancy?

I have two nodes. I want to run job manager and task manager in both. But I get the following errors in the attachments. It tries to get connected on the master from a random node.

I tried the following configs too. taskmanager.rpc.port: 6124 taskmanager.rpc.bind-port: 6125 taskmanager.data.port: 6126 taskmanager.data.bind-port: 6127 Thanks, Deniz Gursoy Worldline, Cardlink, GoPay and Santeos are registered trademarks and trade names owned by the Worldline Group.
