a couple of folks mentioned they made it work. Though we have not set a working example

otlp http works on port `4318` so try exposing this port at docker-compose <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/docker-compose.yaml#L66>

also, enable port `55681` which is the legacy http port for otlp http. Checkout <https://github.com/jufab/opentelemetry-angular-interceptor/blob/main/collector/docker-compose.yaml#L23-L26>

you might want to add `cors_allowed_origins` attribute at <https://github.com/SigNoz/signoz/blob/develop/deploy/docker/clickhouse-setup/otel-collector-config.yaml#L9|otel-collector-config> as in <https://github.com/jufab/opentelemetry-angular-interceptor/blob/main/collector/otel-collector-config.yaml#L1-L8>

and restart otel-collector using
```sudo docker-compose -f ./docker/clickhouse-setup/docker-compose.yaml restart otel-collector```

<@U03369H2U8G> try these out and let us know if this works or not. Else will try to put up a sample repo in your frontend language

I tried by adding the config but did not help <@U01HWQ1RTC2>

Getting response as 501 Not Implemented

what about `<http://localhost:4318/api/traces>` and `<http://localhost:55681/api/traces>`
