//Run in PowerShell as Admin
net stop winnat
net start winnat
iisreset -stop
netsh interface ipv4 show excludedportrange protocol=tcp
Running `net stop winnat` cleared excluded ports
Disable Hyper-V:
dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
After the required restarts, reserve the port you want so Hyper-V doesn't reserve it back:
netsh int ipv4 add excludedportrange protocol=tcp startport=3001 numberofports=1
Reenable Hyper-V:
dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All
The port is busy, you probably have another
project running and you don't remember it :)
