Ok, IAC, my installation works.

However, I cannot connect to SQL Server.

When I launch SSMS, I see the Server type is Database Engine. That is ok. I see the Server name to be the instance name I have provided in the installation. That is ok. I see the authentication to be Windows. That is ok. I see it is pre-selected in read only to the user I have selected. That is ok. However, clicking on Connect fails.

After a while, I have this network-related or instance-specific error.

This is getting annoying.
