Importing Bootstrap in Custom Print Format Causes PDF generation failed because of broken image links

In my custom print format when I add bootstrap and try to generate pdf the following error occurs
frappe.exceptions.ValidationError: PDF generation failed because of broken image links
when I remove the bootstrap everything goes fine. But I must use bootstrap. I have added host_name in site-config.json, I have libssl-dev installed, all other custom print format works well while generating pdf when there is no bootstrap.

Frappe Framework: v14.x.x-develop () (develop)
OS: Ubuntu 22.04
