graph.microsoft.com from Oracle PL/SQL - Certificate Validation Failure
We have an Oracle PL/SQL program that consumes Sharepoint Online data through graph.microsoft.com.
All the setup on Oracle side (i.e. wallets / root and intermediate certificates and/or proxies) was done a while ago and the program used to connect to Graph and used to fetch data at predefined intervals, but only until June 29, 2023 13:16:01 GMT/UTC.
From that time we started getting an Oracle error (ORA-29024: Certificate validation failure) stating that there is something wrong with the certificate chain.
We have already checked graph.microsoft.com's certificate chain, but nothing changed in the root and intermediate certificates we already had.
Is anyone aware of any changes performed on graph.microsoft.com on June 29, 2023 around 13:16:01 GMT/UTC?
