Thank you for reporting this issue, @lukolszewski. @alzimmermsft could you take a look at fixing this TTL problem?

Thanks for filing this issue @lukolszewski.

Have a quick question before I dive further into this. Does the proxy that you're using have an authentication requirement? If it does, could you check what happens if that is disabled for a test run that replicates the same flow when using proxy authentication.

Hi, Thank you for looking into this. Our proxy doesn't require authentication (it is authenticated based on the client IP). I hope this answers the question.
