Facing ICMP Port unreachable Issue.

[Lokesh Nandanwar]

Hi All,

I am facing below ICMP Port unreachable exception when my application docker container is trying to send Jaeger spans to the Jaeger Container.

All below required properties I have already added in the application.

logging.level.io.jaegertracing=DEBUG
opentracing.jaeger.udp-sender.host=jaeger
opentracing.jaeger.udp-sender.port=6831

Caused by: java.net.PortUnreachableException: ICMP Port Unreachable
