Trying to install PDM Server (2018 SP3). SQL and PDM are installed on separate virtual servers. Running on Windows Server 2016. A new SQL admin account has been created by IT for running PDM on the SQL server. When installing PDM server I get the following error:

Error 27502. Could not connect to Microsoft SQL Server "ServerName". [DBNETLIB][ConnectionOpen (SECDoClientHandshake()).] SSL Security error. (18)
