C# raven not sending events

Hey, I am new to sentry and was looking at the C# setup guide which seemed quite simple. However I cannot see the issues under sentry.io (Not sure they are sending, or if they get blocked from sending by the network).
When exception is called, this is all the code:
var ravenClient = new RavenClient(“DSN”);
ravenClient.Capture(new SentryEvent(textInfo));
Running this on localhost and .NET 4.0

was port 443 that was blocked. If anyone know how to send over 80 or 88, then fire me a message else please mark as closed
