<@U08GZJ30Q9X> When I upgraded to latest community Helm chart version (Signoz and K8s infra), it seems the logs/metrics/traces has stopped. I checked the K8s infra pod logs.

```helm upgrade signoz-k8s-infra signoz/k8s-infra --set global.clusterName=&lt;clusterName&gt; --set otelCollectorEndpoint=signoz-otel-collector.signoz.svc.cluster.local:4317 --presets.logExporter.enabled=false --global.cloud=aws -n signoz```
Above is the command I used to upgrade the K8s infra helm chart.

Can you check whether signoz-otel-collector is reachable?

<@U08GZJ30Q9X> On checking the logs of signoz-otel-collector, i got this error message. However, the pod is still in "Running" state.

<@U08GZJ30Q9X> Seems like the error was with the post-upgrade SigNoz chart. I used below command to upgrade SigNoz helm chart.
```helm upgrade signoz signoz/signoz -n signoz --set global.cloud=aws --set global.storageClass=gp2 --set signoz.configVars.clickHouseUrl="<tcp://signoz-clickhouse.signoz.svc.cluster.local:9000>"```

<@U08U0DY2LJY>, That error will go away once you log in to the platform
