Since WordPress 5.5 upgrade REST API not working on live website

Hi,

Since WordPress 5.5 upgrade, the REST API is returning:

woocommerce_rest_cannot_view

On the live website (ex: live.com)

However — on a 100% clone of the website as a staging website (ex: staging.com), the REST API works fine

What could be happening?

I tried:

– Creating new keys on live website
– Creating new keys using a different user
– Using authentication in the URL (ex: consumer_key=x&consumer_secret=x)
– Using basic authentication

Thank you
