I have created a server using WCF and BasicHttpRelayBinding using the following address:
HttpsRelayAddress = ServiceBusEnvironment.CreateServiceUri("https", "mynamespace", "myservice name"");
One of the reasons for using Azure relay is so you can go through firewalls etc. I have this server working fine at home but when I am in the office I am getting the following error when doing host.Open(): No connection could be made because the target machine actively refused it
Now I am assuming the the corporate firewall might be blocking it or something. I don't understand though because I have programs like Evernote that are calling out on port 443 and I can see that in Fiddler. When I watch in Fiddler and start my program up I see nothing. Does that mean it is not even getting out of my machine and it is not an external firewall that is stopping it?
I know it is trying to use port 443 because to start with it was complaining about the port being used and I had to turn off an option in VMware that was using it.
Any ideas please? Is it possible that some types of network calls go through a firewall on 443 and some don't?
