We are witnessing an issue in one of our customer environment (configured under proxy) where in few data packets is not reaching caller environment using service bus relay. In the WCF trace logs we see packet being sent out of source machine but not being
acknowledged at receiver end.
Is there a way to see whether packet actually reach service bus relay based on correlationId or activityId present in WCF logs along with timestamp and service bus dns or do we need any additional logging to achieve this?
Any reason why we might see this behavior, packet being shown as sent in wcf trace but not reached the consumer?
Network team from Customer side claims they have whitelisted *.servicebus.windows.net DNS and we see this happening only for few packets in regular pattern.
We analyzed whether size of packet cause the issue at proxy end but we have received packets of higher size than the one which is blocked.
Let me know if you need any more details.
Thanks in advance!
