I tried to search for 14502 port usage, but it turns out that it is not the port in use.  
I rebooted my computer and tried reinstalling node.js, but to no avail.

I am using it on windows. What should I do

😥😭😭😭

To me the IP address of `0.0.0.0` is a flag there is something else going on.

It might be reserved

`netsh int ip show excludedportrange protocol=tcp`
