Hi camaran,

please have a look around in the forum, using the Forum - Search with the term "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" ( Search result: http://talk.plesk.com/search/82487/?q=Connection+reset+by+peer:+mod_fcgid:+error+reading+data+from+FastCGI+server&o=date&c[node]=208+676+735+677 )

You will notice, that such issues ( in combination with wordpress ) are mostly related to missing/incorrect rewrite rules for the domain - specific nginx configuration, when using PHP-FPM to serve php - files over nginx. It helped a lot in the past, to use the additional Plesk extension "htaccess to nginx" ( description: "Convert apache htaccess rewrite rules to nginx rewrite rules automatically." ).


If you still need assistance, please post your ".htaccess" - file from your wordpress - installation and the depending webserver - configuration files from

/var/www/vhosts/system/YOUR-DOMAIN.COM/conf​

...for further investigations.

Hi camaran,

please check again your webserver configuration. When I check your server, the response is:

HTTP Status Code HTTP/1.1 200 OK
Server nginx
Date Sun, 12 Apr 2015
19:16:46 GMT

To check your webserver configurations, please go to: "Websites & Domains > YOUR_DOMAIN.COM > Web Server Settings" ... you can now check, what NGINX settings you made and if you would install the mentioned "htaccess to nginx" you have as well the immediate choice to convert your current .htaccess file with it ( Link would be on the right of the box for "additional nginx directives", if "htaccess to nginx" - converter is installed ).

 

[nMLxTMJTZ]

I have nginx proxy but php is in fastCGI from Apache

And work with .htaccess.

Can you help me to fix this problem?

Hi camaran,

you only stated

my wordpress installation in plesk some times give me:

... which doesn't resolve to the real issue. This could be as well an issue from your used subdomain "cdn.XXX.im" on the same server ( which is a bad idea, btw... ), or the used cache - plugin(s) and it's configuration(s). To investigate the issue, we really need more error - log - entries ( and used URL(s), which has been used, when the issue appeared ).
Are you able to reproduce the error, when you open a certain wordpress - site on your server? Or is it more an issue, which appears here and there?
Did you as well have a look at the php-fpm - error - log on your server, when you experience the issue?

 

[nMLxTMJTZ]

Hi you can check chatme.im/phpinfo.php

I not have other log and I have this error sometimes in work-login.php I refresh page and work

It's very random

Cdn.chatme.im it's only a cdn alias

 

[UFHH01]

Hi camaran,

please delete your file "phpinfo.php" now, for security resons.

You find errors and depending access - logs for your domain at: "/var/www/vhosts/system/YOUR_DOMAIN.com/logs/"

Is the page "work-login.php" part of wordpress, because I don't know such a page in a normal wordpress installation? Please post the content ( without any login - credentials, please... I write this in addition, because I assume, that the page might be a direct-login page? correct me, if I'm wrong. ^^ ).

Hi,

[Sun Apr 12 14:26:08 2015] [error] Premature end of script headers: index.php

how i can fix? it's very random

Are you running ModSecurity with high security settings perhaps?

 

[nMLxTMJTZ]

Hi, sorry the page is wp-login.php i wrote from iphone
I attach my mod_seccurity setting and you can see the log file here https://www.dropbox.com/s/cvlvejdp4wn30vm/logs.rar?dl=0

 

[UFHH01]

Hi camaran,

could you please check the permissions for your file "work-login.php", because it seems, that this file has wrong permission settings. The permissions should be as followed, when using Fast-CGI:

YOUR_DOMAIN-SYSTEM-USERNAME-AS-DEFINED-IN-PLESK:psacln

( owner:group )​

If you have SELinux enabled, please follow the suggestions on this KB - article:

FastCGI does not work with SELinux enabled ( KB - article 125 072 )
