Hi Team,

While am running the below PowerShell code getting the below error for few host IP's

New-SSHSession : An established connection was aborted by the server

request you to provide some solution

Code to connect to Cisco Devices

$userId = ""
$pwd = Get-Content "$userId.Pw.txt"
$pwd1 = ConvertTo-SecureString -AsPlainText $pwd -Force
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList $userId, $pwd1
#$enable = Get-Content "enable.txt"

$hostnames = Get-Content "<path/file>"
$ErrorActionPreference = 'Continue'
foreach($hostname in $hostnames)
{
$A = $ssh=New-SSHSession -ComputerName $hostname -Credential $cred -Force -OperationTimeout 300 -ConnectionTimeout 300
if ($A)
{
$ErrorOccured=$False
$stream = $ssh.Session.CreateShellStream("dumb", 0, 0, 0, 0, 1000)
$stream.Write("terminal length 0n") $stream.Write("show inventoryn")
$stream.Write("show ip int brief | ex unassn") $stream.Write("sh version | i Versionn")
$stream.write("enablen") $stream.write("<enable>n")
$stream.Write("show runn | i comm`n")
Start-Sleep -Seconds 5
$streamoutput = $stream.read()
$streamoutput |Out-File "<path\file>"
Remove-SSHSession -SSHSession $ssh | Out-Null
}
else
{
#write-host "Something went wrong"
}
}

Start with the reported PowerShell script and reproduce New-SSHSession against an affected Cisco host, comparing it with hosts that connect successfully. Investigate the server-aborted connection at session establishment; done means identifying a reproducible cause and documenting an actionable fix or the missing diagnostic information.
