Powershell to check different ports on different servers

Question

Good Day All,

I am powershell noob and can't figure out how to make this code working

$servers = @{
  'google.com' = (80,8080)
  'gmail.com' = 443
  'google.it' = 8080
}
$ProgressPreference = 'SilentlyContinue'
$servers.Keys |
    ForEach-Object{
        Test-NetConnection -ComputerName $_ -Port $servers[$_]
    }

If I make 2 rows for "google.com" it do not work, I should have a loop for each port, but I cannot figure how.

Any suggestion?

Thank you and best regards

$servers = @{
   'google.com' = (80,8080)
   'gmail.com' = 443
   'google.it' = 8080
 }
$ProgressPreference = 'SilentlyContinue'
$servers.keys | ForEach-Object  { 
    $site = $_ 
    $servers[$_] | ForEach-Object  {
         "Testing {0} - {1}" -f $_, $site 
         Test-NetConnection $site -Port $_  
    }
}

Maybe this is helpful:

$servers = @(  
    [pscustomobject]@{ServerName='google.com';Port='80'}  
    [pscustomobject]@{ServerName='google.com';Port='8080'}  
    [pscustomobject]@{ServerName='gmail.com';Port='443'}  
    [pscustomobject]@{ServerName='google.it';Port='80'}  
    )  
    
foreach ($server in $servers) {  
    $ServerName = $server.ServerName  
    $Port = $server.Port  
    Write-Output "Testing $Port on $ServerName"  
    Test-Connection $ServerName -TcpPort $Port  
    }

Slightly longer than the other suggestions:

$servers = [ordered]@{
    'google.com' = 80, 8080
    'gmail.com'  = 443
    'google.it'  = 8080
}
$servers.GetEnumerator() |
    ForEach-Object { # for each host
        $server = $_.Key
        $port = ""
        $_.Value | 
            ForEach-Object { # for each port
                $port = $_
                Try {
                    $tcp = (New-Object System.Net.Sockets.TcpClient).Connect($host, $_)
                    [PSCustomObject]@{
                        Host = $server
                        Port = $_
                        OK   = $true
                    }
                }
                Catch {
                    [PSCustomObject]@{
                        Host = $server
                        Port = $port
                        OK   = $false
                    }
                }
            }
    }
