Synch secondary to primary error

Just setting up free version before moving to Pro – our primary to secondary test connection is OK but secondary to primary fails with this error

<p>The document has moved <a href=”https://www.yoggiebear.nz/wp-json/wc/v2/?consumer_key=invalid&consumer_secret=invalid”>here</a&gt;.</p> 

I see it mentions the invalid key so on primary, I deleted the original and created a new rest API connection (twice actually) with the same result.

Any ideas?
