Hello, I followed the instruction from docs to install signoz in kuberntes. I used different namespace (signoz) and different release name (signoz-dev). I installed the example also using this singoz example. Signoz has been installed properly. I just change values of ingress only in values.yaml file. But I am facing error
something went wrong
. The log of otel is below:

Hi @Mukesh Chaudhary! Can you list of all pods?
kubectl -n signoz get pods
can you also share the
overwrite-values.yaml
?

@Mukesh Chaudhary That's strange.
signoz_traces
database should be created by OtelCollector's
clickhousetraces
exporter. Works fine for me.
Can you share K8s and Helm version?
Also the signoz chart version.

@Mukesh Chaudhary tested with same versions of K8s and Helm.. No issues here.
It is possible that OtelCollector pod started before the clickhouse pod though there is init container to wait for it.
can you try to delete the exist otel-collector pod?
Copy code
kubectl -n signoz delete pod signoz-dev-otel-collector-67f955bc75-4jz2k
