Unable to establish Web Stream - Service Bus Example

Question

I'm trying to run all the service bus examples, in my office we behind the firewall and proxy. So, I'm using the below code to avoid the error "Unable to reach servicebus.windows.net via TCP (818, 828) or HTTP (80, 443)"

<system.net>
    <defaultProxy useDefaultCredentials="true">
    </defaultProxy>
</system.net>

But still I'm getting the below error if I use any other binding other than "netOnewayRelayBinding". Please suggest me how to run other examples without getting the below error. If I'm using "netOnewayRelayBinding" the service is running fine.

System.ServiceModel.CommunicationException was unhandled

Answer 1

Hi

I am also facing this error. I am using NetEventRelaybinding.

But it is intermittent.

Answer 2

Thanks Prashant for confirming this. Interestingly I'm not getting this error when I'm running the samples from Home Broadband. Need help to get away this problem in Office.

Answer 3

Hi Murty,

Could you try modifying your config file in the following way to discard any AutoProxy configuration issues?

<system.net>
  <defaultProxy useDefaultCredentials="true">
     <proxy bypassonlocal="True" proxyaddress="http://your_proxy_server:80" />
   </defaultProxy>
</system.net>

Answer 4

Hi Cesar,

Thanks for your advice, I tried with this code for all the bindings from my office environment. With this extra line of code "<proxy bypassonlocal="True" proxyaddress=http://my_office_proxy_server_IP:80 />" now I'm not getting either an error or any response just the program is not terminating at all.

With regards to netOneway either I use the above line or not the program is working. Need something to be solved here?

Thanks
