Sitecore docker build. Invoke-RemoteScript.ps1 times out - docker

Question

Working on this for over 2 weeks and I'm run out of ideas.
Hoping for some1 experienced with dockerized Sitecore.
I have a Sitecore Docker (windows container) build and i'm trying to run script on it.
Sitecore is built with this tutorial: http://rockpapersitecore.com/2019/10/yet-another-sitecore-docker-series/
Script:
Write-Host "Preparing for DB upgrade"
Import-Module C:\automation\SPE
$session = New-ScriptSession -Username admin -Password b -ConnectionUri http://localhost
$jobId = Invoke-RemoteScript -Session $session -ScriptBlock {
Install-Package -Path C:\automation\CT_DB_upgrade.zip -InstallMode Merge -MergeMode Merge
} -AsJob
Start-Sleep -s 5
Wait-RemoteScriptSession -Session $session -Id $jobId -Delay 5 -Verbose
Write-Host "CT_DB_upgrade.zip installed"
Stop-ScriptSession -Session $session
More over script suppose to update clean DB with tables for our Sitecore connector.
Script works fine, tables are added and Sitecore works, but...script times out..
After "CT_DB_upgrade.zip installed" it runs for about 2min and times out.
Normally on VM script runs for about 0.5/ 1 sec and doesn't crash.
PS C:\automation> .\install-ct-db.ps1

As i understand it crashes at: Stop-ScriptSession -Session $session.
I have tried changing different web.config settings, like timeouts, but even if i set timeout after 10min it will timeout anyway after around 2min.
Here is ConvertFrom-CliXml.ps1:
function ConvertFrom-CliXml {
param(
[Parameter(Position=0, Mandatory=$true, ValueFromPipeline=$true)]
[ValidateNotNullOrEmpty()]
[String[]]$InputObject
)
begin
{
$OFS = "`n"
[String]$xmlString = ""
}
process
{
$xmlString += $InputObject
}
end
{
#This try catch ignores rest of the code and let script finish with no error.
#try {
$type = [PSObject].Assembly.GetType('System.Management.Automation.Deserializer')
$ctor = $type.GetConstructor('instance,nonpublic', $null, #([xml.xmlreader]), $null)
$sr = New-Object System.IO.StringReader $xmlString
$xr = New-Object System.Xml.XmlTextReader $sr
$deserializer = $ctor.Invoke($xr)
$done = $type.GetMethod('Done', [System.Reflection.BindingFlags]'nonpublic,instance')
while (!$type.InvokeMember("Done", "InvokeMethod,NonPublic,Instance", $null, $deserializer, #()))
{
try {
$type.InvokeMember("Deserialize", "InvokeMethod,NonPublic,Instance", $null, $deserializer, #())
} catch {
Write-Warning "Could not deserialize ${string}: $_"
}
}
$xr.Close()
$sr.Dispose()
#} catch {
# Write-Host "Could not finish script correctly"
