Django wkhtmltopdf loading stuck

Question

same issue. Just checking if it has been solved. More context: I'm using django-wkhtmltopdf 3.3.0 and wkhtmltopdf 0.12.5 (with patched qt) on ubuntu.

options = {
    'title': "PDF Title",
    'page-size': 'A4',
    'orientation': 'portrait',
    'margin-top': '20mm',
    'margin-right': '10mm',
    'margin-bottom': '20mm',
    'margin-left': '10mm',
    'load-error-handling': 'ignore',
    'quiet': None,
    'enable-local-file-access': True,
    'header-spacing': 5,
    'footer-spacing': 5,
}

When I run this command, my server gets stuck with this message:

Loading pages (1/6)
[=================>                                          ] 29%

If I ctrl C my server, I can see the command that was running:

/usr/local/bin/wkhtmltopdf --enable-local-file-access --encoding utf8 --footer-spacing 5 --footer-html /tmp/wkhtmltopdfap_vk62a.html --header-spacing 5 --header-html /tmp/wkhtmltopdfhfdro6i1.html --load-error-handling ignore --margin-bottom 20mm --margin-left 10mm --margin-right 10mm --margin-top 20mm --orientation portrait --page-size A4 --title "PDF Title" /tmp/wkhtmltopdfku94woo9.html - 

The latter works fine when execute on bash (or python shell).

Thank you random stack overflow shell deities.

Seems the problem is from static files loading.

wkhtmltopdf tries loading the static files from "localhost:8000/static" but that port is already busy, awaiting to respond to the query calling wkhtmltopdf. Some sort of mutual exclusion.

Edit: I fixed this by adding moving the static files to an nginx server on port 8081, and serving them from there.
