Hi Rune, I am getting a "No such host is known" while trying to upload a file to S3. Up until yesterday it was working fine, but since I get this error. The code runs fine from my local machines, but not from appharbor.
I tried upgrading libraries, but its not that.

System.Net.Http.HttpRequestException: No such host is known.
