title: UWP App throwing error while calling await httpClient PostAsync request
body: <p>I am trying to get a response from await httpClient.PostAsync(uri, content) in a uwp app and it was working fine and after almost an year the uwp app stopped working and started throwing exception. The end point is not receiving any hit, so i suspect it is not even going out through the host laptop. Can someone help on this. I have the capabilities(internet/enterprise authentication check marked) . I have also done the loopback exempt for the package and verified it  using  <em>CheckNetIsolation.exe LoopbackExempt -s</em></p>
