[BUG] Connect-PnPOnline will not work after multiple runs

[2nh]

Reporting an Issue or Missing Feature

I am in the process of running some test for downloading/uploading files to SharePoint online.
These are automation scripts that run without any user interaction.

I start my day out perfectly fine. All code and functions are running as expected. Able to perform MULTIPLE tests that work flawlessly.
However after a couple of tests I am unable to run Connect-PnPOnline

I am authenticating with a certificate thumbprint.
Connect-PnPOnline -Url $SiteURL -ClientId $ClientID -Thumbprint $cert.Thumbprint -Tenant $TenantId

Error:

Connect-PnPOnline : An error occurred while sending the request.
At line:1 char:1
+ Connect-PnPOnline -Url $SiteURL -ClientId $CilentID ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Connect-PnPOnline], HttpRequestException
    + FullyQualifiedErrorId : System.Net.Http.HttpRequestException,PnP.PowerShell.Commands.Base.ConnectOnline

I have noticed that SOMETIMES when I close out of PowerShell ISE and relaunch it connects back again. But most of the time this does not resolve the issue.

I am also running Disconnect-PnPOnline after every download/upload is completed.

Expected behavior

Expected behavior is for it to connect to PnP online and receive an access token.

Actual behavior

Code will sometimes connect to PnPOnline fine.
After a couple of runs it begins to fail.

I have tried running the Connect-PnPOnline inside of a function, outside of a function.
I have tried to store the connection within a variable. No luck.

Steps to reproduce behavior

To reproduce the behavior I run my script multiple times.

It will begin to error out randomly on the Connect-PnPOnline.
I run multiple tests on different sites but it will always find away to error out eventually. Not sure what I am doing wrong.

    Try {
        $cert = Get-ChildItem -Path Cert:\LocalMachine\My\ID
        
        Connect-PnPOnline -Url $SiteURL -ClientId $ClientID -Thumbprint $cert.Thumbprint -Tenant $TenantId
        Write-Host -f Green "Connected to PnP Online..."

        $Files = Get-PnPFolderItem -Connection $connection -FolderSiteRelativeUrl $SourceFolder -ItemType File
 
        foreach($file in $Files){
            Try{
                Get-PnPFile -Url $file.ServerRelativeUrl -Path $TargetFolder -Filename $file.Name -AsFile -Force
                Write-host -f Green "Downloaded the File: "$file.Name
            } Catch {
                Write-host -f Red "Error Downloading File: "$file.Name
            }
        }

        Disconnect-PnPOnline
        Write-Host -f Green "...Disconnected from PnP Online"

    } Catch { 
        Write-Host $_
        Write-host -f Red "Error Downloading Multiple files"
    }

PnP.PowerShell Version 1.11.0

Which operating system/environment are you running PnP PowerShell on?

• [x ] Windows

• MacOS

as soon as I submitted this bug script worked fine for 100+ tests.
I removed some dependencies that were being loaded prior to calling function.
Closing this out.
