It includes a relational database engine, which stores data in tables, columns, and rows. Please, see How to configure screen saver timeout in Windows, how to Fix EFI network timeout on VMware Workstation, and “Microsoft SQL Evaluation period has expired: How to upgrade SQL Server instance“.

This was not resolved because connection seems to work but the authentication method I tried to use is not supported by the database instances and therefore did not work. I was trying to connect using Domain Account and this was not supported.Moreover, I hope you found this blog post on the Fix MSSQL Connection timeout and timeout period expired helpful.
