Unhandled Exception:
System.NullReferenceException: Object reference not set to an instance of an object

so, exception occurred in using (Stream responseReading = response.GetResponseStream())
my guess - possible response is NULL.

here.
//Anything that doesn't return error 200 throws an exception. Sucks. :l
response = (HttpWebResponse)we.Response;

sorry:

//Anything that doesn't return error 200 throws an exception. Sucks. :l
response = (HttpWebResponse)we.Response;
//TODO: Handle timeouts, etc?

           Console.WriteLine(we.ToString());

look like crazy!

Ah, yeah the standard SSL/Mono cert problem. You can also use mozimports for this iirc.

http://stackoverflow.com/questions/3285489/mono-problems-with-cert-and-mozroots etc.

from slackapi.

As a note, the code:

ServicePointManager.ServerCertificateValidationCallback = (a, b, c, d) => { return true; };

Ignores validation on all SSL certs regardless of if they're valid or not. This is a security hole for your application as a whole.

from slackapi.

yes. its true. but I want to be sure what issue is here.
thank you so much, dev!

from slackapi.

No worries, thanks for reporting this.
