DR Web UI "Schedules" page is showing this error "Error: Unable to run command (Operation timed out after 45 seconds with 0 bytes received)."
Executing "schedule --show --replication" is also showing the same error.
The replication container needs to contact back to the source IP at TCP port 9904 to obtain the replication schedule.
Either the connection back to the source IP at TCP port 9904 is being blocked or the source IP set is being incorrect. (This can be due to a source IP change that is not pushed down to the replication target container)
Check if the firewall is open for TCP port 9904 from the replication target DR to the source DR.
Check if the source IP setting for each container is correct using the following command:
replication --show --verbose
If the source IP is incorrect, please update the source IP at the replication container.
