PID4 (system32/ntoskrnl.exe) blocking the port 80

[RaySa]

Hello,
when I run my site i get a message: Heads-up! Local’s router is having trouble starting. Learn more
When I google the Internet: I realize the System uses Pid 4 (for port 80) in task manager, and of course, since it is a system file there is no way to end it. I read so many posts on the internet about this, none could help. I even do not have
Microsoft Windows [Version 10.0.19043.1288]
(c) Microsoft Corporation. All rights reserved.

C:\Users\Reza>netstat -nao | find “:80”
TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4
TCP 10.0.0.77:61723 151.139.128.14:80 TIME_WAIT 0
TCP [::]:80 [::]:0 LISTENING 4

C:\Users\Reza>

Pid4 is a system file.

Sounds like an issue I was having a while back with the BranchCache service hogging port 80, try disabling that maybe?

Windows Issue: Local's router is having trouble starting

I was having significant difficulty with Local’s router failing to start after upgrading to 5.2.3, same issues with attempting to bind to port 80 while currently in use. After doing some research, I found this article, which was incredibly helpful: http://www.devside.net/wamp-server/opening-up-port-80-f Turns out the BranchCache Windows service was hogging port 80 to itself in my case. Disabling the service fixed the issue.

"In most cases, Local can’t start the router because there is something already occupying port 80. There are only two options to get things working:

1. Set Local to use localhost Router Mode.
2. Stop whatever is already listening on port 80 and restart Local."

   I would do the first one: Set Local to use localhost Router Mode (preferences, advanced, router mode: localhost)
