Azure event hub processor doesn't work with enterprise proxy - azure-eventhub

Question

I am working with Azure event hub sender and processor tutorial and I'am sitting behind a enterprise proxy.
Sending events to the event hub works really fine, but i have problems to let get eventHubProcessor access to the Azur event hub. It seems to me that I have some proxy problems.
I use
DefaultEndpointProtocol=https
as storage connection string and I set
ServiceBusEnvironment.SystemConnectivity.Mode =
ConnectivityMode.Https;
I also tryed many different variations to set the proxy in App.config file. E.g.
<configSections>
<sectionGroup name="proxyGroup">
<section name="basicProxy" type="Proxy.Configuration.CustomProxySection, Proxy" />
</sectionGroup>
</configSections>
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true" >
<proxy usesystemdefault="true"/>
</defaultProxy>
</system.net>
Witout any success :(
At "eventProcessorHost.RegisterEventProcessorAsync(options).Wait();" I get the exception
InnerException:
HResult=-2146233087
Message=Der angeforderte Name ist gültig, es wurden jedoch keine Daten des angeforderten Typs gefunden

Does anyone has an idea??
Many many thanks for your time.

Reason for the problem is that ServicePointManager does not support proxys in case of HTTPS.
To solve the problem change everything to HTTP
In your main program:
string storageConnectString=string.Format("DefaultEndpointsProtocol=http;....");
ServiceBusEnvironment.SystemConnectivity.Mode = ConnectivityMode.Http;
In your App.config
<system.net>
<defaultProxy enabled="true" useDefaultCredentials="true" >
<proxy
autoDetect="false"
bypassonlocal="true"
proxyaddress="http://##.###.###.###:8080"
usesystemdefault="false"/>
</defaultProxy>
</system.net>
