I fixed the issue by adding the following line before calling the SharpRaven code
WebRequest.DefaultWebProxy = null;
I also found that you can go in to Internet Explorer Lan Settings and tell it not to Auto Detect the proxy settings. But going in to a computer in our office that I know is really close to a basic Windows 7 install I can see that it appears to be set by default. This means I probably need a programmatic way to solve this. I am not sure if our internal server which hosts our DNS/DHCP is causing this issue or not, but I am going to just assume a proxy is not required for our customers. This may be a bad assumption as I don’t know much about proxies but I am more comfortable with disabling proxies than having this released and having it take forever to send the error logs to Sentry. I probably should look in to creating a config setting to allow users to turn back on the use of proxies in case someone requires one.
