[BUG+Report] Random 502 Bad Gateway + fastcgi://127.0.0.1:9001 + ntoskrnl.exe

martinandersen3d

I have found a problem, that I don't know how to solve. Maybe it should be examined and fixed in an update?

Within the last few weeks I startet getting a lot of random "502 Bad Gateway".

As the admin suggest, look in the laragon/bin/nginx/nginx-1.16.0/logs/error.log

What I can see is that the fastcgi is running on Port 9001.

After a fresh reboot, and without starting laragon in server mode. I did run a check on port 9001:

Start powershell (maybe in admin mode)
Get-Process -Id (Get-NetTCPConnection -LocalPort 9001).OwningProcess

In my case it prints like this:

#######################################
Handles NPM(K) PM(K) WS(K) CPU(s) Id SI ProcessName

5794 0 204 3568 25.34 4 0 System
######################################

I look up the PID (Process Id in task mannager)

There is this exe file called:
C:\Windows\System32\ntoskrnl.exe

This exe file is using port 9001, and will conflict with Laragon i guess?

It is some kind of system file I think.

Here are people with similar problem (note the date of this github issue is recent):
https://github.com/cretueusebiu/valet-windows/issues/131
https://github.com/eclipse/mosquitto/issues/1580

I maybe think it is something that has come in a windows update.

How have I desperately split testet the problem:

I used chrome, firefox
I flushed my dns
I Created a new Laragon-wordpress-install
problem is still there.

I don't know how to move the fastcgi port and I don't know what to do with ntoskrnl.exe

I think a lot of users is affected by this

In this thread he talks about some Intel driver, maybe? :

Solved.

This is a intel graphics card software related issue on windows 10.

How to fix:

In windows, go to:

Start menu
Type: Services:
Find the service called: "Intel(R) Graphics Command Center Service"
Right click > Properties > Startup type = Disabled
This fixed the problem for me..

[Edit]
It looks like windows update will re-enable the feature

I managed to fix the problem by installing a new version of the Intel driver from here (version from September 15, 2020):

Intel acknowledged that the issue of used port 9001 was a driver usue back in July, and they said it would be fixed with that driver update:

I had the same problem and it took me days of searching.
Port 9001 and 9002 were blocked by another application. I was not able to change these ports due to limited permissions.
In the file "laragon\etc\nginx\php_upstream.conf" I changed the line
server 127.0.0.1:9001 weight=1 max_fails=1 fail_timeout=1;
to
server 127.0.0.1:9003 weight=1 max_fails=1 fail_timeout=1;

Now everything works, no more 502 errors.
