`listen EACCES: permission denied in windows`


Hi anyone who comes here and don't find any answer. I have an answer that I think will help. it fixed the issue for me. there is cases where nothing is running on the port but some applications or even your code can not run the fix to this is in this order:

Open PowerShell as Admin.

stop winnat with command below:

net stop winnat

start winnat again with command below:

net start winnat

this fixed the problem for me in many cases. no restart needed. I hope it will help you too.
