Paul_Huijbregts On a2016 we have some issue with the new mode in an environment working with proxy.
We are on 10.8048.22439.1065 with HKLM\software\policies\microsoft\windows\DataCollection TelemetryProxyServer and DisableEnterpriseAuthProxyconfigured
Sense event viewer log shows: Failed to communicate with authentication service. register request failed, hresult: 0x800706BE, HTTP error code: 0 .
Checking with MDeClientAnalyzer show me the following :
PS C:\TEMP\MDEClientAnalyzer\Tools> .\MDEClientAnalyzer.exe
Proxy config: Method=TelemetryProxyServer, address=proxy.*.com:8080

On one server I tried to set winhttp proxy and it seems to work but setting up the winhttp proxy completly break the purpose of TelemetryProxyServer configuration.
