External zipkin

how do i send traces to a url endpoint where zipkin is running outside the cluster ?

    meshConfig:
      enableTracing: true
      defaultConfig:
        tracing:
          zipkin:
            address: https://external-zipkin.example.com

This doesnt work.

Thanks for the help

@richard_moss have you tried adding a ServiceEntry for https://external-zipkin.example.com ?

I experience the same problem, but i have no idea to resolve it.

istio not support: https://external-zipkin.example.com:30000, only support external-zipkin.example.com:30000
