Order sync not working

Good day,
the automatic filling of tracking numbers from Aliexpress has not been working for a few days now.
I tested it and:
– if I click on the arrow in the order details in the administration (attachment fig. 01), the tracking number will be downloaded
– if I click on the AliExpress sync button in Woocommerce → orders (attachment pic 02), it will add all the tracking numbers
– when I manually started the cron to start Order Sync, nothing happened

What with this?

Thank you for your help.
