PROBLEM WITH DIGITAL PRODUCTS

Hello, these days I am having a failure with the Packlink plugin, specifically with digital products that have NO shipping, on the checkout page I have a critical error that chatgp has identified with the following:
Server en.poslovnipaket.com is causing an SSL failure with CERTIFICATE_VERIFY_FAILED.

requests.exceptions.SSLError: HTTPSConnectionPool(host=’en.poslovnipaket.com’, port=443): Max retries exceeded with url: /xml.php (Caused by SSLError(SSLCertVerificationError(1, ‘[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006)’)))

The fact is that no type of shipment should come out since it does not have any shipment assigned to that product since it is digital, but it seems that the plugin goes crazy. With products with shipping there is no problem.

can help me pls?

greetings
