Intermittent or no connection established to SQL Server

[Spectre-007]

#Steps to reproduce

Create a connection to a SQL Server and run a command from the SQLserver module
$connectionString = "Server=<servername>,14481;database=hoclusters;Integrated Security=True;Persist Security Info=True;User ID=$user;Password=$pwd"
$sqlConnection = New-Object System.Data.SqlClient.SqlConnection $connectionString
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.Connection = $SqlConnection
$SqlCmd.CommandTimeout = 0

invoke-sqlcmd -serverinstance '<servername>,14481' -database 'master' -query "select @@servername" -QueryTimeout 60

Expected behavior

invoke-sqlcmd command to return server name after successful connection

Actual behavior

A connection is established but the pre-login handshake times out

Did I do something wrong with the initial issue report?

[mklement0]

Your problem sounds like it may be specific to your environment as opposed to exhibiting a problem with PowerShell itself - only the latter issues should be reported here.

Perhaps the "Support" link on the new-issue page (https://github.com/PowerShell/PowerShell/blob/master/.github/SUPPORT.md) may have given you the idea that posting a support question here is appropriate.

I agree that the information there is misleading, which has been pointed out before (/cc @SteveL-MSFT).

Here's the relevant information:

---

If you believe that you've found a problem with PowerShell itself and have reproducible steps to demonstrate it:

• Search the existing issues to see if your problem has already been reported.

• If not, make sure you are able to repro it on the latest released or preview version and, if so, create a new bug-report issue with your repro steps.

Otherwise, do not post here and instead ask the community for support:

• Slack and Discord Community Chat - interactive chat with other PowerShell enthusiasts. Both Slack and Discord are bridged via a bot and can seamlessly talk to each other.

• StackOverflow.com and PowerShell.org Forum - search or post new general PowerShell usage questions
