Increase pool size of TCP connections for performance testing

Question

I use JMeter 5.3 for performance testing of web applications on Windows Server 2012 R2. When script was executed I got following error:

Response code:Non HTTP response code: java.net.SocketException
Response message:Non HTTP response message: Connection reset

I updated pool sizes with following commands, but this network issue still persists:

Get-Item 'HKLM:\System\CurrentControlSet\Services\Tcpip\Parameters' | New-ItemProperty -Name MaxUserPort -Value 65534 -Force | Out-Null
Get-Item 'HKLM:\System\CurrentControlSet\Services\Tcpip\Parameters' | New-ItemProperty -Name TcpTimedWaitDelay -Value 30 -Force | Out-Null
Get-Item 'HKLM:\System\CurrentControlSet\Services\Tcpip\Parameters' | New-ItemProperty -Name TcpNumConnections -Value 16777214 -Force | Out-Null
Get-Item 'HKLM:\System\CurrentControlSet\Services\Tcpip\Parameters' | New-ItemProperty -Name TcpMaxDataRetransmissions -Value 5 -Force | Out-Null
