Since updating the SSL certificate for sunpig.com on 28 September, the IFTTT recipe I’ve been using to auto-publish new posts here to Twitter has been failing. IFTTT rejects the url https://sunpig.com/martin/feed/ with a “Not a valid feed url” error. Looks perfectly fine to me. I’m guessing the new certificate (exactly the same issuer as before) has something to do with it, but I’m not going to spend a huge amount of time figuring it out. Maybe it will work again some day, maybe it won’t.
