Cannot bind to some ports due to permission denied

Question

For the last 3 months or so I\'m having random errors where I can\'t bind a specific port where our Identity server is running on my local development workstation. At first

Answer 1

The reason is that Hyper-V takes over these ports, to prevent it from happening do the following:

1. dism.exe /Online /Disable-Feature:Microsoft-Hyper-V (will have to restart)
2. netsh int ipv4 add excludedportrange protocol=tcp startport= numberofports=1
3. dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

The original solution is here.

If after that you still can't bind to the port do the following:

• netsh http add iplisten 0.0.0.0 for IPv4
• netsh http add iplisten :: for IPv6
