Can't use Google Now Reminders?

So I've been playing around with my nexus 5 and overall I'm pleased so far, however whenever I try to add reminders via Google Now, I keep getting the message "can't reach Google at the moment"

This happens on WiFi and mobile data and have rebooted the phone to check if that may solve it (never know...).

I can add reminders via Google Keep however being able to add reminders directly from the home screen simply by talking is so much easier than adding them via Keep.

I've tried looking through the Google product forums however the content never seems to load on the page.

Anyone know if the reminders issue is a common bug or if there's a fix available for this?
