Hello Team, I have installed Signoz as docker container using the docker-compose file I have another application i.e a Java sprint boot application in another docker container. I have executed the following command at runtime : CMD java -javaagent:/build/opentelemetry-javaagent.jar -Dotel.metrics.exporter=none -Dotel.exporter.otlp.endpoint=http://172.18.0.6:4317 -Dotel.resource.attributes=service.name=ct -jar /build/target/CardTopupPaymentService.jar I am getting this error : 080534.260 [main] INFO  com.validus.neobank.card_topup_paymentservice.CardTopupPaymentServiceApplication - No active profile set, falling back to default profiles: default Skipping auto-registration [otel.javaagent 2022-01-07 080547:071 +0000] [OkHttp http://172.18.0.6:4317/...] WARN io.opentelemetry.exporter.otlp.internal.grpc.OkHttpGrpcExporter - Failed to export spans.

@User Is http://172.18.0.6:4317 accessible from the location where you are running your app?

Its the IP address of the container signoz/otelcontribcol:0.4.2

I meant - can you ping

172.18.0.6:4317

from the machine where you are running the java application and see if it is accessible? I am guessing you are running SigNoz and your java application in different machines? @User

Sir it is on my local machine, I have executed the compose file which is given on the github repo. My application is also running as a container on same local machine is same signoz network. When I ran the docker exec command, I am getting the ping response . Kindly find below screenshots for your reference

@User ok, all docker images seem to be running fine @User would you have more insights here?
