Problem with orders.xml

Hello.

Regarding our on-line eshop , our ERP interface for automatic order retrieval used your orders.xml api:

https://store-name/myshopify.com/admin/api/2022-04/orders.xml

which is not working any more

HOW CAN THIS BE FIXED??

P.S I know that json file works but this is not an option for me.

Thank you.
