Unable to connect: Adaptive Server is unavailable or does not exist TinyTds::Error

I'm trying to connect to a remote SQL Server (version 2014) from Ruby.I can connect via a UI Client, so the host, user, and password are correct.

My code looks like

require 'tiny_tds'client = TinyTds::Client.new(host: '172.xx.0.xxx',                             database: 'XXXXxxxxxTEST',                             username: 'sa',                             password: 'Xnforxxxx')results = client.execute("SELECT * FROM XXX_ProcessOrder")

sig@mbp xxx % tsql -CCompile-time settings (established with the "configure" script)                            Version: freetds v1.4.10             freetds.conf directory: /usr/local/etc     MS db-lib source compatibility: no        Sybase binary compatibility: yes                      Thread safety: yes                      iconv library: yes                        TDS version: 7.3                              iODBC: no                           unixodbc: yes              SSPI "trusted" logins: no                           Kerberos: yes                            OpenSSL: yes                             GnuTLS: no                               MARS: yes

sig@mbp xxx % gem list tiny*** LOCAL GEMS ***tiny_tds (2.1.7)

Ans this is the error.

 2024-02-26 16:48:55 - TinyTds::Error - Unable to connect: Adaptive Server is unavailable or does not exist (172.xx.0.xxx) (TinyTds::Error):|   /Users/sig/.rbenv/versions/3.2.3/lib/ruby/gems/3.2.0/gems/tiny_tds-2.1.7/lib/tiny_tds/client.rb:60:in `connect'|   /Users/sig/.rbenv/versions/3.2.3/lib/ruby/gems/3.2.0/gems/tiny_tds-2.1.7/lib/tiny_tds/client.rb:60:in `initialize'|   /Users/sig/Code/xxx/application.rb:10:in `new'|   /Users/sig/Code/xxx/application.rb:10:in `block in <top (required)>'

Am I missing something here?

UPDATE - With the same setup, I can access a SQL Server running locally on Docker.
