Hi,
I’m not really sure when it started and what would be the source cause.
Here is the Woocommerce System Status Report : https://pastebin.com/runF0SLF
And the fatal error logs : https://pastebin.com/8GQLg5Ms
Thanks for your help, I managed to find the problem using some code to debug log the redirection.
In the stack trace, there was an homemade plugin which was intercepting the API call and redirecting to the home page.
Thanks, this ticket can be closed.
