this Problem:

 

• port range check

  netsh int ipv4 show excludedportrange protocol=tcp

  shows it’s in a blocked port range (start 3371 end 3470) is an exclusion
• disabled Hyper-V ( dism.exe /Online /Disable-Feature:Microsoft-Hyper-V )
• tried netsh int ipv4 add excludedportrange protocol=tcp startport=3410 numberofports=1
• failed error message

  “Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird.”

  (Port is used by a program)
• checking the port if it is used 

  Get-Process -Id (Get-NetUDPEndpoint -LocalPort 3410).OwningProcess

  and

  Get-Process -Id (Get-NetTCPConnection -LocalPort 3410).OwningProcess

   

• failed error messages

  Get-NetUDPEndpoint: No MSFT_NetUDPEndpoint objects found with property 'LocalPort' equal to '3410'.  Verify the value of the property and retry.
  Get-Process: Cannot bind argument to parameter 'Id' because it is null.
  
  Get-NetTCPConnection: No MSFT_NetTCPConnection objects found with property 'LocalPort' equal to '3410'.  Verify the value of the property and retry.
  Get-Process: Cannot bind argument to parameter 'Id' because it is null.

any further help getting my Sonos S2 App over the splash icon?
I’m using https://www.glasswire.com/ and disabled it as this sometimes solves things, but not this time..

How do I proceed when I cant set the excludedportrange?
