Hello @enguias,  Sometimes this error could be for an old algorithm such as SHA-1. And most possible if using Java 11 that is more strict with the policies.  One option is to use connection without TLS, if possible and acceptable in your environment:  jdbc:sqlserver://<host>:<port>;databaseName=<DB>;encrypt=disable Or, update the certificate to SHA-256 with TLS 1.2.  This is the best option if you prefer to maintain the encryption.  Maybe this documentation from SQL can help too:  https://learn.microsoft.com/en-us/sql/database-engine/configure-windows/configure-sql-server-encryption?view=sql-server-ver17  ...
