I've installed KnpSnappyBundle on an existing Symfony 3.4 project. I've tested the PDF generator with a HTML twig with text only, no images, no css, no js : it works fine.
Then I've added (to the twig) an image and a Bootstrap.Css file using absolute URL (i'm working on localhost): the PDF generator displays an ugly error :
The process "wkhtmltopdf --lowquality '/tmp/knp_snappy5aeb39ad71e767.56551505.html' '/tmp/knp_snappy5aeb39ad71ebf0.62787578.pdf'" exceeded the timeout of 60 seconds.
What's wrong with the bundle ? I'm using an i7 laptop with 8Gb RAM (ubuntu 16.04), I don't think it's a problem of machine configuration.
UPDATE: I've tested wkhtmltopdf from the command line and it do convert my twig :
wkhtmltopdf http://127.0.0.1:8000/eshop/admin/order/print/2 out.pdf
So wkhtmltopdf have no problems with absolute URLs on localhost !
Thanks
