Why is WebClient DownloadData working on IIS Express but not on IIS?
I have the following piece of code that is getting some data from a url.
WebClient webClient = new WebClient();
byte imageBytes = webClient.DownloadData(url);
The url
variable is just a string but didn't work even if I make it a Uri
.
While this is working fine when I'm running the site using IIS Express, when I load it via IIS the webClient.DownloadData(url)
call is throwing an exception with message: "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond IP:port", where IP and port are the values for the ip and port of the url I'm trying to access.
Also, if I go directly to that url using a browser it works fine. I turned the firewall completely off in case it was blocking the response from the external site but didn't make any difference.
Thanks

Have you tried it with a different URL, for example one at google?

Most obvious difference is that IIS Express runs under your user account whereas IIS will be running under other accounts (that may not have network credentials). Are you running on a home/unmanaged network or a work/managed network environment, where e.g. proxy and firewall rules may be implemented by other network devices?

I'm running it on a work network, behind a proxy. This is failing on my dev machine though
