Due to the posting giving out my OAuth token, I had a page setup that only returned the 204 and I saw the same behavior at the short interval.
The actual API I am using, after setting the timeout to 90 seconds, it fails with an unspecified error, and no hex dump.
Code:
10/10/2014 10:03:40 AM: -------------------- Starting Build: 'quickbits.bld' --------------------
10/10/2014 10:03:40 AM: Building project step 2 - HipChat Send Build Message...
Connecting to HTTP server 'api.hipchat.com' on port 80
Posting data to /v2/room/40983/notification
Unspecified error
10/10/2014 10:04:40 AM: Step '2 - HipChat Send Build Message' failed
10/10/2014 10:04:40 AM: Build ended (elapsed = 00:01:59).
I'll send emails to support to prevent my OAuth token from being publicly posted.
