Hybrid pods fail to start
In hybrid deployments, cloud native event analytics (CNEA) is unable to connect to the backup ObjectServer, which prevents hybrid CNEA pods from starting.
Problem
Resolution
- CNEA is unable to connect to backup ObjectServer either due to blocked IDUC ports that gateway
connects to or due to DNS issues. On the primary ObjectServer, check the IDUC ports that they are
listening on.
