Connection refused means that nobody is listening on port 1433. Have you double checked this?

although its generated a new error

 (UndefinedFunctionError) function Tds.Encoding.encode/2 is undefined (module Tds.Encoding is not available)
    Tds.Encoding.encode("DESKTOP-DQ7NHKS", "utf-16le")

tds module not being available

Better open a new thread. Also post more code and show what have you tried (including library version). Generic questions are usually not answered so please make sure you include some details.

Per the README, make sure you’ve included {:tds_encoding, "~> 1.0"} in your dependencies in mix.exs - just setting the configuration without installing the package would produce exactly the error above.

so i have included it and landed another error

== Compilation error in file lib/tds_encoding.ex ==

You need to install Rust. Apparently the library has a Rust native part.

Do you really need tds_encoding?

Perhaps deleting this dependency from your mix.exs file solves the problem.
