Props for putting the logs in there so they collapse! I love a well formatted post.
The SDK is designed to try to get an operation done until timeout. What I see here is that it couldn’t, for 2.5s, complete the connection and bootstrap. The other thing that looks slightly odd is the number of connections to port 8091.
The way you’ve done the exposed services looks correct. Which Networking Topology do you intend? Also, note that what K8S you’re running on may enter into it, as you won’t always have a LoadBalancer available.
Two other bits of telemetry you may want to check out: the operator logs themselves and if you want to validate the networking setup, this is sometimes easier done with SDK-Doctor which will do active probing and checking.
