Network error on powershell SQL job step - sql

Question

This is partially my code and partially from others help here on stack overflow.
$excelFile = "C:\ExcelTest\Test.csv"
$functionDirectory = "C:\foldername"
$csv = Import-csv $excelFile -Header FileName
Import-Module sqlps
foreach ($line in $csv)
{
if(test-path -path ($functionDirectory + "\" + $line.FileName))
{
invoke-sqlcmd -inputfile "C:\foldername\filename.sql" -serverinstance "servername\instancename" -database "databasename"
}
}
I had to remove the specific serverinstance / servername for privacy but I've checked both of those several times and I don't think that is where the issue is. I keep getting the error
A network related or instance specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections.
I have double checked server / instance name which I got from the server by running
select ##servername + '\' + ##SERVICENAME
nd the database name obviously was easy to get. I have double checked that the server is set up for remote connection (even though this is a database that is local on my laptop and not a remote server currently).
I'm kinda at a loss for what else to check for.
I had read you should look at firewall settings but I don't think those should make a difference when its a local server on my machine.
I'm still somewhat new with SQL and powershell so I apologize for any blatant syntax or formatting errors (please point out so I can correct them). Any help would be appreciated.

Answer 1

Turns out I needed to remove the instance name and just use the server name.
