Cannot bind to some ports due to permission denied

I also had the Hyper-v/WSL problem above, but found a simpler solution:

I had stopped docker before doing this, not sure if it's necessary.

Run as admin:

net stop winnat
net start winnat

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=<your port> 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
