Hi all, I'm facing some issues while running signoz for the first time in a k8s cluster. Basically the only thing that works is the log section. Services, traces and service map are always empty also after running the hotrod sample app. The only errors I can find are: • in otel agent: Err: connection error: desc = "transport: Error while dialing: dial tcp 10.254.210.2294317 connect: connection refused" • in clickhouse instance: Table doesn't have any table TTL expression, cannot remove. Do you have any tips? Thanks

• in clickhouse instance: Table doesn’t have any table TTL expression, cannot remove.
This is harmless.
• in otel agent: Err: connection error: desc = “transport: Error while dialing: dial tcp 10.254.210.2294317 connect: connection refused”
This looks like a n/w issue.

were you able to send data from your application? Or Is nothing working for you?

nothing work except logs. hotrod sample application seems to not send any data but the troubleshooting container doesn't show any error https://signoz.io/docs/install/troubleshooting/#kubernetes
