Timeout when trying to get WNS channel

Question

Hello,
I am trying to use Windows Notification Service behind a proxy.
i opened route described by Microsoft to use the service

<CloudServiceDNS>
<DNS FQDN="*.notify.windows.com"/>
</CloudServiceDNS>
<ClientDNS>
<DNS FQDN="*.wns.windows.com"/>
<DNS FQDN="*.notify.live.net"/>
</ClientDNS>
<CloudServiceIPs>

but when i try to make

channel = await PushNotificationChannelManager.CreatePushNotificationChannelForApplicationAsync();

I have an timeout exception
My application is a uwp application, created based on tutorials, enrolled with ms store and all is ok with it on a personnal laptop.

When i make a trace on my proxy, it seems windows try to access to https://login.live.com/ppsecure/deviceaddcredential.srf.

My question is: Is login.live.com access mandatory to get a wns channel?
If not, how can i resolve this channel?

Thanks by advance for your help

Hello, Welcome to Micorosoft Q&A,

My question is: Is login.live.com access mandatory to get a wns channel?

It's necessary to get the channel, and https://login.live.com/ppsecure/deviceaddcredential.srf looks like redirect uri. Derive from Windows Push Notification Services (WNS) overview document, https://login.live.com is the host that use to receive authentication request for wns.

POST /accesstoken.srf HTTP/1.1  
 Content-Type: application/x-www-form-urlencoded  
 Host: https://login.live.com  
 Content-Length: 211  
   
 grant_type=client_credentials&client_id=ms-app%3a%2f%2fS-1-15-2-2972962901-2322836549-3722629029-1345238579-3987825745-2155616079-650196962&client_secret=Vex8L9WOFZuj95euaLrvSH7XyoDhLJc7&scope=notify.windows.com  

For your scenario, we suggest you add above host address in the white list.
