Issue Nginx stopping each day, at same time

[Gabor H]

Hi,

Having issue with Nginx. Websites on the server giving 502 Bad Gateway issue each day, nearly similar time at early morning.
Nginx is up and running. Status is green, enabled.
When I check the error log, I see only these kind of errors. (my IP masked)

2016/09/21 07:41:19 [error] 22856#0: *41591 connect() failed (111: Connection refused) while connecting to upstream, client: 66.249.76.81, server: , request: "GET /hundewelt/5013350-trixie-sicherheits-adressanhanger-4-cm-4011905013350.html HTTP/1.1", upstream: "http://XX.X.XXX.XXX:7080/hundewelt/5013350-trixie-sicherheits-adressanhanger-4-cm-4011905013350.html", host: "pfoetchenshop.eu"

Got a new server almost a week ago, with new IP. These GET's could be related to the previous owner of the IP.
But why is Nginx giving the 502 issue only early mornings? Any idea?

Hi Gabor,
check out this kb article...

https://kb.plesk.com/en/128431

• For Debian based systems:
  
  Replace 'apache2 reload' with 'apache2 restart' in /etc/logrotate.d/apache2 file.
  
  
• For RHEL based systems
  
  Replace 'httpd reload' with 'httpd restart' in /etc/logrotate.d/httpd file.

I hope that helps.
Kind regards

Lloyd

UPDATE>

Strange things happening here. Found out that in httpdocs the nginx configuration file for WP is gone, and a .htaccess is generated.
And the 502 issue is came in because in Hosting Settings I've set FPM served by Nginx.
(if I change it to FPM served by Apache, then 502 issue is gone)

So, the big question is, that why Nginx configuration file disappeared by the night from httpdocs?

Hi Lloyd,

Why is it necessary to do anything with Apache setting, if I've set FPM served by Nginx?

And pls see a kind of anomaly written above.

Gabor.

onnect() failed (111: Connection refused) while connecting to upstream

Indicates that Apache is down.
I'm not sure what you mean by "Nginx configuration file disappeared by the night from httpdocs"?
There is no Nginx configuration file equivilent to .htaccess.

Ok, I'll look around again what's happening there.

Anyway, apache is needed to run and config anything related to apache, when Nginx is used
and FPM application served by Nginx?

Hi Gabor,
yes exactly, even if one site is using Nginx-FPM, other things like File Sharing and Webmail need Apache and FastCGI.
Once you have made that modification I suggested, let me know tomorrow if you have the same problem.
Hope it helps
Kind regards

Lloyd
