Greetings i'm facing a strange activity I cannot comprehend.
The 2% of https traffic is reporting in application pool logs that statuses:
In C:\Windows\System32\LogFiles\HTTPERR i see only Timer_ConnectionIdle messages.
On firewall logs i can see some RESET CONNECTION events i don't figure out.
Why i have a substatus code with a value but not a status code?
When i can face a 0 value? when the server does not return a response at all?

0 is not a valid http code. I have not seen that before. I would check again in failed request tracing to see what it is producing.
Also can you recreate at all and see what the client gets back.
win32 = 64 though mean that there is some (likely) network issue with the request being sent back to the client. It does not mean there is a problem it could be that the clients last acknoledgement package from client was not received but the desired traffic
was sent out from the server.

I activate the failed request tracing for all error status and I compared IIS logs with these new detailed trace and the logs are related to 403.7 Mutual SSL authentication with a client not using the correct certificate.
