Often you'll see in the IFTTT activity log that request timed out, but it actually worked. I suspect there is something else wrong with the sequence which is failing.
Have you populated your IFTTT key in your user settings? If so, also double check it is correct. To find your key, go to this page and take the URL component after https://maker.ifttt.com/use/
Let me know once you've checked the key is correct.
