I had:
OSError: wkhtmltopdf reported an error:
Exit with code 1 due to network error: ConnectionRefusedError
and that fixed it.
Thanks.

Hi, Can you elaborate on your solution? with steps.

6

On your server, access the site_config.json file located at:

frappe-bench/sites/{yoursitenamehere}/site_config.json

and add the following line:

"host_name": "http://127.0.0.1:8000",

The following command will work when your are in your site’s directory to edit site_config.json:

sudo nano site_config.json
7

It worked for me by adding local IP:

“host_name”: “http://192.168.x.x”,

in site_config.js file

where can i find the site_config.js file in the Django project?

I found this solution/explanation in github, and i had updated my configurator service in compose.yaml which i’m using with a custom image:

bench set-config -g host_name “http://${CUSTOM_IMAGE:-frappe/erpnext}-frontend-1:8080”;

worked perfectly, hope this help someone! :slight_smile:

11

will this work with

wkhtmltopdf 12.6 version as well ?

12

Thanks it worked.
I had the same problem but with pdf email generated by cronjob.
It was really difficult to discover because from client side worked fine but from cronjob it doesn’t

13

But when we work with domain name then what we need to set , because if we set “host_name”: “http://127.0.0.1:8000”, then able to open pdf but anywhere i used frappe.utils.get_url so it will get this http://127.0.0.1:8000 and mke wrong url so how can it correct

Maybe it can still help you or someone else who stumples about this or related error.
When you’re using your domain you should add either “http://your-domain.com:80” or “https://your-domain.com:443”. When your domain is the frappe site name at the same time, it could be necessary to remove the domain entry from your /etc/hosts.
