Installing Archivematica problem: Failed to establish a new connection: [Errno 111] Connection refused"

[Alberto Villalobos]

Hello,

I recently started to install Archivematica, but I got this message: "Failed to establish a new connection: [Errno 111] Connection refused".  I am following the "Automated installation using Ansible" (https://www.archivematica.org/en/docs/archivematica-1.17/admin-manual/installation-setup/installation/install-ansible/#install-ansible).  

Thanks in advance for your help!

Alberto.
