View 1 RepliesToday at 12.50 pm my (ubuntu 14.04.1 LTS) server running plesk 12.0.18 suddenly stopped serving websites. Any attempts to access a webpage on any vhost returned the 502 bad gateway using Nginx error messsage.When I looked at the nginx logs, I found messages like:
2014/10/30 14:48:00 [error] 3099#0: *101 connect() failed (111:
Connection refused) while connecting to upstream, client: m.m.m.m, server: , request: "GET /server-status HTTP/1.0", upstream: URL....
Restarting apache & nginx (/etc/init.d/apache2 restart & /etc/init.d/nginx restart) made no difference and I had to reboot to restore http access.
Strangely if I browsed with port 7080 specified (i.e. http://n.n.n.n:7080), this worked fine for all vhosts, so apache (which I believe is listening on this port while nginx listens on port 80) is working fine - nginx is just not able to pass stuff to it?
this is a fresh Plesk 12 installation on a Dedicated Server, on Debian 6. I haven't installed a License key yet.When i tried to run MIgration Manager, the loading was taking forever. Also, when i try to enter Webserver Configurations Troubleshooter, i get 502 Bad Gateway nginx error.In the /var/log/sw-cp-server/error_log i get this error:
Code:
2015/06/17 11:42:47 [error] 3918#0: *52 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: A.B.C.D, server: , request: "GET /modules/configurations-troubleshooter/index.php/index/list HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "X.X.X.X:8443", referrer: "https://X.X.X.X:8443/admin/module/list?context=modules"
When i try to insert a Plesk License, i also get this error:
Code:
2015/06/17 10:29:17 [error] 5643#0: *81 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: A.B.C.D., server: , request: "POST /server/

I followed this KB article 118757 but no luck. Also, the server resources are at the lowest usage and there is >2 TB disk space available.
We have a problem with a magento website. Often (perhaps when we use administration), we have the message "502 Bad Gateway nginx".
We have added server instructions in Plesk Nginx:
proxy_buffers 16 16k;
proxy_buffer_size 32k;
fastcgi_buffer_size 32k;
fastcgi_buffers 16 12k;
But we have still the problem.
We have tried :
[URL] ....
And
[URL] ....
Without results...
The log file say:
[client x.x.x.x] client denied by server configuration: /var/www/vhosts/domain.com/httpdocs/app/etc/local.xml
x.x.x.x is the website IP.
I have a server with the latest version of plesk and centos.
The main site is Articoli Promozionali
Until now kept on the server active both apache and nginx.
Tonight I tried to disable apache leaving only nginx.
That raises the error: 502 bad gateway NGINX at all sites on that server.
To use nginx i need to keep active apache?
What can cause that error?
i have plesk panel 12 ... in the last few days there was a automatically update from plesk for my strato v-server.
After this update i got the message: 502 Bad GateWay - nginx when I will connect to my plesk login ...
all websites etc works fine but i can't login ...
Since we switched to Plesk 12 and activated nginx the problem reoccurs reliably on every domain change.
As soon as a customer creates a new domain or alias and Apache restarts nginx delivers 502 errors for maybe 10 seconds. After that everything is fine again.
The system is Debian 6.0.10 with Plesk 12.0.18 Update #38
That might not be a problem in small environments, but with >100 domains the timeout is annoying enough for customers to pick up the phone.
Adding this to /etc/sw-cp-server/config did not do the trick.
http {
fastcgi_buffers 32 32k;
fastcgi_buffer_size 64k;
fastcgi_read_timeout 600;
fastcgi_send_timeout 600;
}
We are running Plesk 12 (latest version) on openSuse 13.1. The web server is nginx as a proxy in front of Apache. We are running into a 502 Bad Gateway nginx error when trying to send data from a simple form to a php script.
The log shows: upstream prematurely closed connection while reading response header from upstream
It seems that Plesk does not configure nginx properly as some pages, especially pages that are accessed via https have broken headers. The headers of a page that is displaying
HTTP/1.1 400 Bad Request =>
Server => nginx
Date => Sat, 26 Jul 2014 09:53:13 GMT
Content-Type => text/html
Content-Length => 166

Today morning a logged in in plesk without problems and started Fail2Ban and closed it. Now I want logged in and get only 502 bad gateway. All Domains working fine and shell access working fine too.
What happen here? What can I do?
When I turn on nginx for the server I am able to browse non SSL protected sites correctly. I receive a 502 Bad Gateway error on any sites that have an SSL certificate. Is there a fix for this? I have been unable to find one.
I am running Plesk 12 on an Ubuntu server.

Yesterday I've upgraded the server to Plesk 12.0.18. After the upgrade, a WHMCS install has stopped working.
The only error logs where I found errors is the proxy_error_log. It contains this kind of lines (for the 502 error):
2014/08/13 08:13:45 [error] 2918#0: *400 upstream prematurely closed connection while reading response header from upstream, client: XX.XX.XX.XX, server: XXXXXXX.COM, request: "GET /knowledgebase.php HTTP/1.1", upstream: "http://XX.XX.XX.XX:7080/knowledgebase.php", host: "xxxxxxxxx.com"
Plesk 11.5.30 all latest updated installed is used with Power-User view on an Ubuntu 12.04 LTS 64 Bit system.
The Plesk Interface is working well in general. But if the customer clicks on "Webspaces" -> Add Webspace they run in a:

To try to fix it with:
/usr/local/psa/admin/bin/nginxmng --disable
/usr/local/psa/admin/sbin/httpdmng --reconfigure-all
/etc/init.d/apache2 restart
/etc/init.d/ngnix restart ( does not work anyway since the customer is not using it ) -> ngnix_enable=no
Which did not work ( ngnix is and was not active )
In the log /var/log/sw-cp-server/error.log
we can see:

this is my first thread because a big Problem after Plesk update from 10.2 to 12.0.8.
Always i got a bad gateway when i try to reach https://domain:8443
The only mistake i cam see is after /usr/local/psa/admin/sbin/httpdmng --reconfigure-all
is

It seems last night Plesk ran any update and it failed. I received an mail with a link to the log, but I cant access Plesk Panel to see the log.
When trying to access Plesk, I get "502 Bad Gateway" Message.
Inside the Log there are many errors like:
Code:
2014/12/18 15:26:51 [crit] 14416#0: *3563 connect() to unix:/var/run/sw-engine.sock failed (2: No such file or directory) while connecting to upstream, client: xxx.xxx.xxx.xxx, server: , request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "xxxxx:8443"
Is there any way to disable auto updates for plesk?
under Plesk 12.0.18 PHPMyAdmin is failing to import a 3 MB SQL dump of a simple Joomla website. "Error 505 Bad Gateway", it says.It happens with other dumps too, some as small as ~500 KB. The format (SQL or ZIP) of the file uploaded doesn't seem to matter, because the upload itself seems to work; it seems it's the post-processing what is raising the error.
The funny thing is that the import itself seems to work (the contents of the SQL dump are imported), but the error message appears and causes confusion and support requests from our clients./var/log/sw-cp-server/error_log says:
2015/05/15 03:19:31 [error] 10215#0: *5 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: XX.XX. XXX. XXX, server: , request: "POST /domains/databases/phpMyAdmin/import.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "xxxx. xxxxxxx.com:8443", referrer: URL.....To me it sounds like a timeout.
This seems to be a "popular" error among Plesk users, and I have tried this, this and this with no luck.
As I read, when Plesk and WHMCS are in the same server, you may have 502 bad gateway errors when creating an account through WHMCS..Page not Found/Timeout/502 Bad Gateway error creating accounts with Plesk 10+..By default Plesk 10 and above performs a forced restart of apache when an account is created or suspended which causes WHMCS to lose connection to the server, and if your WHMCS is on the same server, you will also lose connection to WHMCS at the same time.
In order to resolve this please refer to the following knowledgebase article for instructions on configuring Plesk to perform a graceful restart instead: URL..
But when I activate nginx in Plesk the 502 bad Gateway problem comes back.Is there an option to activate Nginx graceful restart in Plesk?
I have a strange issue on a Plesk 12 VPS. Sometimes the sites result in a "502 Bad Gateway (nginx)". This happens 1 or 2 times a day on different times.
In the httpd log I see a record "can't apply process slot" and in nginx log I see "connect() failed (111: Connection refused) while connecting to upstream" but restarting apache and/or nginx will not always result in a working site.
When I restart iptables everything is working fine again.
My current version of nginx in plesk 11.5.44 is 1.5.0 and i would like to update it to the latest stable version which is 1.6.0. However, i cannot seem to manage to do so. I tried with yum update nginx but i receive Package(s) nginx available, but not installed.

View 6 Replies View RelatedMy server admin already upgraded my OpenSSL to version 1.0.1m 19 Mar 2015 and he also upgraded Nginx to 1.6. I'm also running CentOS v5.11 and Plesk v11.5.
However, he tells me that he still can't get TLS 1.2 to work because he noticed that my server uses a different version of Nginx (sw-nginx), which he believes is part of Plesk. How we can get TLS 1.2 working on the Plesk copy of Nginx (sw-nginx)?
Plesk 12 will not do it and if you reinstall it you get errors after installation. Maybe a bug but seems nobody is interested in answering my question before.
I tried to remove by
apt-get remove --purge sw-nginx
dpkg -r sw-ningx
Both of them display that is removed but after a new installation are the folders not created and maybe old files not overwritten if not deleted.
I wanted to activate nginx on my server als describes on [URL] ...
Installing was no problem, but when i try to enable nginx, I always get errors:

Is here a tutorial special for plesk 12 that show me how set nginx to show real visitor ip in access_log and php?
Actual nginx show for IPv6 visitors the own server IPv6 in access_log and php.
how is it possible that after an update my main site is down? This site: www.orderhosting.it has plesk Panel and I have 20 sites. They work perfectly but my main site is off. I think there is an error in the configuration because:
[root@orderhosting ~]# grep -r 199.99.36.73 /etc/nginx/
[root@orderhosting ~]#
This is strange.Error log does not report any errors, only this: [warn] RSA server certificate CommonName (CN) `Parallels Panel' does NOT match server name!?
