We have installed an app on a number of Surface Pro devices for my client. After installation, the app is unable to connect to the backend service. The following details the configuration:
- The apps are installed on Surface Pro 2 devices running Windows 8.1 Professional with an Enterprise Sideloading License
- The devices are connected to the company's corporate domain wifi network.
- The service is hosted on the same domain network
- The network has a proxy configured via the following PAC file:
function FindProxyForURL(url, host) {
// URLs within this network are accessed through
if (shExpMatch(url,"*checklistapp.uhs-pruitt.com/*")) {return "DIRECT";}
if (shExpMatch(url,"*asgs01.uhs-pruitt.com/*")) {return "DIRECT";}
...
// All other requests go through port 8080 of proxy.example.com.
// should that fail to respond, go directly to the WWW:
return "PROXY wsas360-01.uhs-pruitt.com:80; DIRECT";
}
- The proxy requires authentication when not using a DIRECT connection
- When using this PAC file, the app cannot connect to the service (which is at https://checklistapp.uhs-pruitt.com/Service ), despite the fact that netsh shows that the app is using a direct (no-proxy) connection.
- The app connot connect if last line of the PAC file is changed to
DIRECT; PROXY wsas360-01.uhs-pruitt.com:80
- When hard coding the proxy (The url below is hosted at 10.100.255.250), the app is able to connect
