502 Bad Gateway while click on Webspaces -> Add Webspace

I

isp4p

Basic Pleskian
Hi,

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:

URL:
https://server:8443/smb/account/create-subscription

Browser:
502 Bad Gateway
nginx


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:

[error] 1936#0: *180 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 84.177.142.220, server: , request: "GET /smb/account/create-subscription HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "server:8443", referrer: "https://server:8443/smb/account"


Any idea how to fix that ?

Thank you and greetings
Oliver
 
Hello,

Please try to add following setting in your nginx.conf file

Code: 
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
 
Hi,

thank you for your advice.

The ngnix deamon is not active:

/etc/init.d/nginx start
* Not starting NGINX as it is disabled in config

And its not supposed to be active, nor it was active before.

So i assume that changing in

/etc/ngnix/nginx.conf

will not do anything.


Or am i wrong ? Does the sw-cp-server require ngnix ?

Thank you !
Greetings
Oliver
 
Hello,

Can you please try this setting after enable the nginx on your server and let check if you are still facing the same issues in you Plesk panel
 
hi,

/usr/local/psa/admin/bin/nginxmng --enable
/usr/local/psa/admin/sbin/httpdmng --reconfigure-all
/etc/init.d/apache2 restart
/etc/init.d/ngnix restart
/etc/init.d/sw-cp-server restart

proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;

inserted.

Result:

502 Bad Gateway
nginx

Errorlog:

hi,

if it helps:

Switching from Poweruser to Service Provider overview gives for Adding clients / Domains:

[error] 23472#0: *14 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 84.177.141.63, server: , request: "GET /admin/subscription/create HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "server:8443", referrer: "https://server:8443/admin/domain/list?context=domains"

with 502 ngnix.

I too have the exact same problem after upgrading from 11.0 to 11.5! Is there anything we can do?
 
Hi,

yes, with us it happen also with an update.

The very last update: Panel Version: 11.5.30 Update Nr. 18 / OS: Ubuntu 12.04.3 LTS


Brings:

[error] 23472#0: *92 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 87.148.151.45, server: , request: "GET /smb/account/create-subscription HTTP/1.1", upstream: "fastcgi://unix:/var/run/sw-engine.sock:", host: "server:8443", referrer: "https://server:8443/smb/account"

After appport as application run several seconds on 100% CPU.

As it seems we will have to install a new server and migrate the accounts.

Its sad that it seems none of the officials cares about such problems.

Greetings
Oliver
 
I have checked all possible log files

So there seems to be a problem with libmysqlclient16...

Any help?

So I guess I found the problem. I have updated my Lucid 10.04 Ubuntu server with PHP 5.4.20 and MySQL 5.5 by using launchpad repositories which installed a new libmysqlclient18.

So after trying to install a new myodbc for my Ubuntu 10.04 (with possible support for libmysqlclient18 or so?) I gave up and tried one last thing... copying libmysqlclient_r.so.16 and libmysqlclient.so.16 from another server to the one with the problem. An guess what - it works. So the problem probably comes from libmysqlclient18?

I'm currently facing exactly the same sympthoms. However, i don't think, that they're related to the MySQL thing, since i havent found any error in sw-engine.log.
