Yet another wkhtmltopdf thread

Hi folks,

I’m experiencing a similar issue, if not the same one, as discussed below: Help Needed: Error with PDF Generation when Sending Email.

I’m unable to send emails using my Gmail account, and I also can’t print invoices. I have already set the host_name to my site name, which is proxied through Nginx Proxy Manager, but the issue persists.

Has anyone found a solution or have any suggestions on what else I might try? Thanks in advance for your help!
