I can connect to the database in Microsift SQL Server Management Studio, but had no joy hooking up DBeaver to the db. I was however able to connect DBeaver to my Docker MSSQL db instances so I was a bit flumoxed.
The answer as ever was provided in Stack Overflow, and a link to the following posts.
And from all the way back in 2007 – but still relevant :
MSSQL doesnt enable TCP/IP connections by default so you have to set that up and manually give it a defined port number (unless you want it to dynamically change on each startup).
