Hey Guys,
I'm currently trying to set up a REST webservice using the Azure Service Bus Relay and an WebHttpRelayBinding. In general it is working fine, most of the time the requests are forwarded to my local endpoint by the Service Bus Relay. Though every now and then I recieve a 502 Bad Gateway from the Service Bus Relay. Those errors occur more often during load testing (about 25% of 200 simultaneous requests do fail).
The errors doesn't really give a lot of information, as they are looking like this..
<Error><Code>502</Code><Detail>Bad Gateway. TrackingId:fe7108cd-5565-40a5-b357-dd78b3b2453c_G48,TimeStamp:10/8/2015 7:50:35 AM</Detail></Error>
<Error><Code>502</Code><Detail>Bad Gateway. TrackingId:f842c6b9-a38a-416a-b6aa-fcf8e262b1d8_G61,TimeStamp:10/8/2015 7:50:36 AM</Detail></Error>
I'm currently using https as scheme and when switching to http the failed requests occur somewhat less often but are still present. Furthermore i'm doing this in a cooperate network (proxy & firewall).
Has anyone got an idea on this or are there any suggestions on what i can try next to investigate and fix this problems?
Thanks in advance,
Frederic
