So from my own sleuthing, I deduced it was an error with my hosting preventing IFTTT from connecting. I was hosting with DotEasy.
Since I was just setting up my site, I had the liberty to switch to WP.org’s recommended Bluehost and that worked….
So, it’ not much help but it seems like you might want to contact your hosting company.
Same problem here and just made a new thread about it shortly before you.
I have tried everything that others have posted. Any luck addressing the problem?
I’m having the same issue and just posted about it last night. Did anyone get this working for wordpress.org?
