Yes, There should be another collector

clickhouse-setup_otel-collector-1

running? Are you sure ClickHouse is running properly.

Yes, I looked at and mentioned the missing collector

clickhouse-setup_otel-collector-1

. And please make sure ClickHouse is ready to accept connections. You can check logs of clickhouse container to see if there are any errors.

Restart and make sure

clickhouse-setup_otel-collector-1

container is running and this error will get fixed.

perfect

I found the problem, signoz-clickhouse was using port 9000, the same as portainer, so I have stopped Portainer, and restart signoz-clickhouse and signoz-frontend, now is OK.
