Wkhtmltopdf always resolves /var/www/vhosts/default/htdocs/index.html

J

Joe_Knighting

New Pleskian
Hi,

I am running wkhtmltopdf on one of my CentOS 6 boxes running Plesk 12.

I have used Plesk since version 10 and up until November 2014 this worked as expected.

Wkhtmltopdf is a tool that uses webkit to generate a PDF version of a web page using command line. It works as expected for all sites that are not hosted on the same server that it is running on. However for anything local it will always resolve the same file as a PDF. (/var/www/vhosts/default/htdocs/index.html)

I have tried adding the domain with loopback to /etc/hosts file as suggested on the wkhtmltopdf Github Issue tracker, however after pinging the domain, although this does change the domain from resolving the external IP of the server to the loopback address (127.0.0.1) the same page is always found and generated by wkhtmltopdf.

I'm sure this is an issue with Plesk's virtual hosts, but I'm not sure where to start to try to identify the problem? Does anyone have any ideas or could give me some advice please?
 
From suggestion on the wkhtmltopdf issue tracker, to eliminate it as the problem I tried the following:-

Code: 
wget -O /tmp/test 'http://www.domain.com'

This returns the same redirect page found in /var/www/vhosts/default/htdocs

Therefore it must be an issue with the configuration within Plesk/CentOS. Can anyone suggest anything?
 
More info, this is a problem with Nginx I believe. If I run:

Code: 
curl -v -i www.domain.co.uk

Which returns this:

Code:

Hi Joe_Knighting,

I am a bit surprised, that you investigate your issue without any logs, which normally point to issues and failures. Instead you try to investigate your issue, by using wget and curl and don't even mention, what the output of ( for example! ) "wkhtmltopdf http://YOURDOMAIN.com YOURDOMAIN.pdf" is and if you installed as well "xvfb" in order to have a working "wkhtmltopdf" installation.
