Then, you can then navigate to http:https://localhost:16686 to access the Jaeger UI.
Jaeger Openshift templates: https://github.com/jaegertracing/jaeger-openshift
Open the application on port 8080. At this point, the application will try to flush the spans into jaeger. If there are any connection issues, you'll see something like in the application log:
io.jaegertracing.internal.exceptions.SenderException: Failed to flush spans.
at io.jaegertracing.thrift.internal.senders.ThriftSender.flush(ThriftSender.java:115)
at io.jaegertracing.internal.reporters.RemoteReporter$FlushCommand.execute(RemoteReporter.java:160)

Caused by: java.net.ConnectException: Connection refused (Connection refused)
otherwise, the application log will successfully create a new Span, like:
