From Linux, can you use isql or similar to test connection?
Thanks for your reply. Yes, I can connect to it using the sqlcmd command line tool and create a database. I can also do same using SSMS.
The problem doesn't see to be with SQL Server but rather .NET SqlClient. I have just spun up a brand new VM with Ubuntu 18.04.3 LTS and the result is identical.
