Commented Issue: Trying to connect to "SQL"... - Fail [19412]

I am running into an issue with an installation on a new VM instance and VM database. When I ran the script for the first time it fails when trying to connect to the Dev (Connection Error. Check server name, port, firewall) and the second time the connection fails but different message (Exception calling “Open” with “0” argument(s): “Cannot generate SSPI context.”) . The error details are not pinpointing much or very detail so I was hoping someone has encounter the same issue and have a solution.

Both servers are in the same domain. I checked the SQL server and insured that all the accounts have access to the SQL Instance; Farm Account and Setup Account have sysadmin rights. The port 1433 is open on SQL's firewall. There is connectivity between the servers.

First Time I ran the script…
- Testing access to SQL server/instance/alias: Dev01
- Trying to connect to "Dev01"... - Fail
--------------------------------------------------------------
- Script halted!
- Connection Error. Check server name, port, firewall.
Press any key to exit...

Second Time I ran the script…
- Creating SQL alias “Dev01,1433”...
-Testing access to SQL server/instance/alias: Dev01
- Trying to connect to “Dev01”… - Fail
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
- Script halted!
- Exception calling “Open” with “0” argument(s): “Cannot generate SSPI context.”
Press any key to exit…

I have been having this problem consistently now and I am here are my steps to create the issue:
* Have a Domain Server nothing but default policies
* Build Default Windows 2012 Server Called WFE Join to Domain
* Build Default Windows 2012 Server called SQL Join to domain
* Install SQL 2012 on SQL Server using Guildlines from Vlad Catrinescu White Paper
* Create named instance SP2013Dev on port 1433
* Create firewall rule allowing port 1433
* Use AutoSPInstaller 387, and AutoSPInstallerGUI create
* Verify port 1433 in open to SQL server
* Makes Sure SPInstall Account is Admin on Both Servers and SQL SysAdmin
* Basic install Specifying Create Alias true Sections as follows
```
<Database>
<DBServer>SP2013DEV_ALIAS</DBServer>
<DBAlias Create="true" DBInstance="SQL\SP2013" DBPort="" />
<DBPrefix>SP13Dev</DBPrefix>
<ConfigDB>Config</ConfigDB>
</Database>
```
* Run AutoSQInstaller

Output:
```
