Are you sure the SHA-IN/OUT settings are correct? SHA-1 selected? As of their documentation nothing has changed and I couldn’t find any evidence that more people got that error now. But there are many discussion and things to try out if you google for “unknown order/1/s/”.

Here are a few:

they have asked me to select “Each parameters followed by pass phrase” option under Global security parameters

Go to Configuration > Technical Information > Data and Origin Verification and enter the base URL of your WooCommerce site, i.e. (if your site uses SSL on the checkout page then don’t forget to include HTTPS in the url: On that same page, enter a SHA-IN pass phrase of your choosing. Then scroll to the bottom of the page and hit “Save”.

Maybe ask the ogone support if they have an idea what’s wrong.
