OK, this was a new one for me. Trying to connect to an Azure database from CF 2016 and got an error: “The SQL server login requires an ssl connection”. This one had me stumped until I found this solution: In the “Connection String” box, enter “EncryptionMethod=SSL;”. It’s in the advanced settings section, I’d never noticed it before. Entering that took care of it though! Thank goodness I didn’t have to mess around with drivers or jar files to fix this.
