DNS ----> Try running “curl -vI http://web.erp.domain”. Once the domain responds, wkhtmltopdf will work without any issues.
Of course, you need to make sure it’s accessible.
In my case, using a proxy, I edited the /etc/hosts file and, instead of using the local server’s IP, I used the proxy’s IP. That’s it—no other changes needed.
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!
Confirm if the site location is accessible from within workers and gunicorn containers. If the process cannot connect to host_name it’ll not be able to generate pdf.
Access from browser is different, that you already have.
Use extra_hosts or figure out way to resolve images from containers.
Thank you for your prompt response! I would appreciate your assistance, and I’ll gladly treat you to lunch for your help. 
I’m currently running Docker with WSL, Portainer, Nginx Proxy Manager, and a Cloudflare tunnel in a container. The frontend is proxied through Nginx and is accessible via the internet through the Cloudflare tunnel. All containers have external site access, so I don’t need to add extra_hosts directives (which I believe have been deprecated). They are utilizing the Docker bridge network. For example, I’m able to successfully run:
curl https://test.menteware.com
Here’s the stack configuration I have set up in Portainer:

Execute this from worker-d
For extra_hosts
Hi @revant_one,
Could you please clarify where I should add the extra_hosts directive? All containers can access external sites and return the expected HTML when I run:
curl https://test.menteware.com
But I’m unsure why I might need extra_hosts in this scenario. Any guidance would be greatly appreciated!
Then image issue need more info. You can exec into the container and do bench --site site.name.com console then try to execute the python functions that are causing problems. Tweak code in console to understand why it triggers error.
