Problem with wkhtmltopdf and fonts Server error

Continuing the discussion from WKHTMLTOPDF Installing Fonts:

Hi, we installed the fonts as explained here:

We receive the following server error when trying to generate a pdf document with the preview api/method/frappe.templates.pages.print.download_pdf:

Does http://erp.betacoop.de resolve to your ERPNext instance? If not,

then try running the following

bench update
bench setup nginx
sudo service nginx reload # might have to run as root

info · December 8, 2014, 8:36am

Yes, it is resolving to the ERPNext instance. the failed to load assets/frappe/css/bootstrap.css (ignore) we receive always. But this has nothing to do, right.?

pdvyas · December 8, 2014, 11:04am

From the server what is the output of curl -I http://erp.betacoop.de/assets/frappe/css/bootstrap.css
I haven’t ever seen ContentOperationNotPermittedError, could this be related to SELinux?

info · December 8, 2014, 2:45pm

from the server where erpnext is installed we get:

HTTP/1.1 403 Forbidden
Date: Mon, 08 Dec 2014 14:43:41 GMT
Connection: close
Content-Type: text/html; charset=iso-8859-1

And from any computer:

HTTP/1.1 200 OK
Date: Mon, 08 Dec 2014 14:43:48 GMT
Server: nginx/1.6.2
Content-Type: text/css
Content-Length: 130312
Last-Modified: Thu, 27 Nov 2014 20:08:03 GMT
ETag: "547784a3-1fd08"
Accept-Ranges: bytes
Connection: close

pdvyas · December 9, 2014, 5:51am

Yes!!
So, it should be 200 OK from the server too. Now this is strange why it is 403. Can you check the nginx logs why it gives 403 from server?

info · December 16, 2014, 7:17pm

We did also this to see if nginx user can access the file:

sudo -u nginx bash
cat /home/erpnext/frappe-bench/sites/assets/frappe/css/bootstrap.css

And it works, so the user nginx has permissions to read the file. But still we get the error.
